Easy Installation Guide: Dual Boot Windows Vista and MAC OS X 10.5 .. Real quick and fool proof

Posted on April 5, 2008. Filed under: Blogroll |


This guide is for information purposes only. The author of the blog is not responsible for any of the unforeseen damages that may result to your system/PC or data after following the instructions on this blog. Also Leopard 10.5 is registered trademark of Apple and for legal usage please obtain a Leopard OS X 10.5 dvd from www.apple.com


This guide wouldn’t have been possible, if not for the following great sites, which I read for almost a month to get this guide up. Not in any particular order

  • Uphuck Forums
  • InsanelyMac Forums
  • OSX86 Wiki.
  • Dailapps.net

Things you need

  1. Desktop/Laptop running Windows Vista. (May run with XP..but not tested.)
  2. iATKOS v1.0 DVD image available from any popular torrent site or google it.(Approx size 2.16 GB)
  3. Windows Vista boot DVD
  4. Optical DVD drive

Before you start…..

    1. InstallWindows OS on your C drive. (primary partition 1)
    2. Create an empty primary partition to use for OS X (Say Partition 2)

    Steps : (Follow these steps exactly..in the same order..)

    • Right click on My Computer and Click on Manage. Select Disk Management. Now Create a new Volume for OSX by shrinking an existing volume. You need atleast 5GB of space and the new volume should show up as Unallocated.
    • Make sure that the partition shows up as Unallocated, else repeat the previous step.
    • Now restart the machine and boot into the Leopard DVD that you burned using the iATKOS v1.0 DVD Image.
    • Press F8 as the countdown begins and type -v at the prompt and hit enter.
    • You should see scrolling text on the screen now. If it stops anywhere then drop a comment and I’ll try to help you out.
    • After a while you should be looking at the Leopard Installer. Follow the instructions on Screen.
    • Once the Loading Bar vanishes Select Utilities -> Disk Utility .
    • Select the Volume you created previously and format it as MAC OSX Journaled Extended. Once the formatting is done the volume is ready for installation.
    • Now Close Disk Utility and Select Utilities -> Darwin Boot. Type Y at the prompt.
    • At the prompt when it asks for the Disk Number enter 0. For the Partition Number if your Leopard Partition is 2nd on the disk, then enter 2 and so on.
    • Accept the following prompts and you should see a success prompt saying that so many block of data were written successfully.
    • Now get back to the Leopard Install Screen. Choose the partition that you made in the beginning and follow the instructions on screen.

    Please don’t select any patches etc during the installation, this is normally the reason for most failed installations. Just the plain install would do.

    • Once the Install is done, reboot with the DVD in the drive. Press F8 at Darwin Boot Loader and type -s and press enter.
    • Execute the following commands :

    fdisk -e /dev/rdisk0
    flag 1

    • Now before the PC restarts remove the DVD. At this point you should be able to boot into Vista normally.

    Note: If you are unable to log into windows, because there is an error which says “winload.exe” corrupted.! Relax. Just insert the Windows VISTA boot DVD into the drive and restart. Click on “Repair computer” once you are inside the DVD and it will automatically detect if a problem exists and suggest “Repair and Restart”. Press the same, and remove the DVD once the PC is about to restart. You should now be able to log in to vista without any problem.

    • Now that we have almost everything running fine, lets proceed with the dual boot setup.
    • Boot into Vista. Copy the chain0 file from the Leopard DVD to C:
    • Open the “Command prompt” with “Elevated Admin” privileges from the Start Menu.
    • Type the following into the prompt

    bcdedit /copy {current} /d “Mac OS X”
    bcdedit /enum active
    bcdedit /set {GUID} PATH \chain0

    In the first command type {current} as it is, literally..nothing else..just {current} with the brackets. In the 3rd command however, replace the {GUID} with the alphanumeric GUID you see in the enumerated list under MAC OS X. You can see this list on your terminal as soon as you type the 2nd command above.

    • Close the Command Prompt and Restart Vista.
    • You Should now be looking at a screen with two options to boot into Mac OSX or Vista.
    • Select Mac OSX to see if you can boot into it. You should see the familiar Darwin boot Loading screen with the timer going down. If you dont do anything, then it counts to zero and again shows the menu screen with Vista and MAC OSX options. Dont panic!

    Again select MAC OS X, and now as the timer counts down, Press F8. You would see a list of partitions on your disk with their names. Select the partition with MAC OSX installed by using up/down arrows and press ENTER.

    • Voila!! your Mac should be booting up as you read this..

    See it was that simple. No more HFS+ and Blinking Cursor errors. Just follow this guide step by step and you should be able to dual boot Windows Vista and Leopard in no time. If you have any questions just drop in a comment, I’ll reply at the earliest.

    For Drivers and Patches I suggest you look at the InsanelyMac Forums.

    hi guy
    thats very nice guid, i was waiting for it since it was disapeared from earlier page. congrate
    i have installed as per your guide but at last at the time of booting osx from dual boot window, i get “chain error”
    vista starts normally, i have copied chain0 file to C: where my vista is installed. I have used seperate partition D: for OSX instead of shrinking.
    pls guid me

    i tried to install mac os x
    after loading all the kext files it stopped at one place showing

    “root device not responding”

    i tried to install mac os x
    after loading all the kext files it stopped at one place showing

    “root device not responding”
    my config:
    cpu :core 2 duo 2.2ghz
    gpu:nvidia gf8600
    hdd:sata 320gb

    […] AMD based machine follow the instructions here to patch your iATKOS v1.0 Image. Special Thanks to I Am Nihilist Hack Attack : Install Leopard On your PC in Just One StepHack Attack : Install Leopard on your PC […]

    OK followed the instructions, but every reboot it always asks for the MAC partition. Is there any way to auto select?

    after all the text is done scrolling, I get to the installation of leopard and it just freezes at the preparing to install leopard screen

    Thanks for the guide, but after doing this I get a “Chain booting error” when selecting Mac OS X… I have no problem booting Vista from my D partition and Windows XP from my C partition… Do I have to do a different BCDEDIT setting? Hope you can help!
    Kind regards,
    Dennis Schoenmaker

    thank you for this,
    when i boot from DVD, i only get as far as an apple logo with spinning wheel at the bottom, the after 1 minute, a small image of a circle with a cross pops up at top and i have waited for hours.

    could you tell me how to solve the problem? all my hardwares are listed compatible


    I had problems tipying the line: bcdedit /set {GUID} PATH \chain0
    Could you tell me what shoud I type on it ? The dual boot is not working; even if I choose OSX goes to windows.



    I had issues too – the bootloader wouldn’t stay open. Try adding this:

    bcdedit /timeout 8

    To give you time to pick MACOSX instead of Windows.

    Other thing is, make sure you put in the GUID for that partition, not your Windows one.

    Hope that helps.

    I can’t locate the iatkos download. Is there any other location?

    I am stucked where you type bcdedit. It always say the boot configuration data store could not be opened. Access is denied.

    Can anyone help?

    my problem is there is no option for the Darwin boot loader in the utilities dropdown menu.. I can select the Darwin boot loader in the customized section of the install but then there is no option to enetr any disk or partition number.. I have tried this install which proceeds successfully but then os x will not load..and nor will vista..
    Any help here
    using iATKOS v1.0i

    After I hit F8 and enter -v, it does start scrolling text, it says something about loading hfs files, but on the third one it just reverts to the “press any key to install Darwin/OSx86” screen. It just does this forever. Any help would be greatly appreciated.

    I Followed the old guide you had here a while ago, how does one go about getting rid of it? i’m assuming its not as simple ad deleteing the new volume that was made for leopard?

    I have tried install leopard on my XPS M1330 laptop
    but when it hits IOAPIC: Version 0x20 vectors 0:23 it stalls
    It does tell me MAC Framework Successfully initialised.

    Laptop had Intel 2 Duo Core
    2 GB Ram
    Integrated Webcam and Biometric finger print
    250 GB of which 50are unallocated for Leopard to use.

    Thanks in advance for any advice

    After I enter the -v option, I do see scrolling text and after the second line of “loading HFS+ /System/Library/Extentions.mkext” is posted my machine reboots.

    Any ideas

    my configs are geforce6200 intel 3.0
    had raid zero on it but thought it was the prob so removed it
    when pressing -v my machine reboots without showing any darwin boot menu watsoever..
    can u help?

    bcdedit /copy {current} /d “Mac OS X”
    bcdedit /enum active
    bcdedit /set {GUID} PATH \chain0

    i have a problem with the third command or i think its with the first, im not sure. i can’t find the guid of the mac installation…all it shows is the windows boot manager and windows boot loader…there’s no MAC OS X..help..thnx

    ok, done with the three command lines..now i have a bootscreen with mac and vista, but when i choose mac, windows still boots up…thanks in advance

    i’ve figured it out with the boot up.i was able to boot to mac but i ended up having a grey screen with an apple logo…stuck for a couple of mins…the thing with the spinning wheel has already stopped…any work arounds?

    thanks for this guide.
    i’m wondering if you could help me with a problem.
    when i type -v to boot from the dvd, i get the error message that it can’t recognize the firewire security mode, and then i get the following message: “still waiting for root device.
    thanks for all and i’ll appreciate it if you could answer me.

    You ever figure out how to fix

    after darwins boot i get this error msg

    System config file ‘/com.apple.Boot.plist’ not found
    please help

    i tried doing this and did everything the guide said and made sure i got iatkos v1.0i. so i followed the guide and installed it and i noticed 2 problems. Everything went fine till i did the command prompt where i do “bcdedit /copy {current} /d “Mac OS X”
    bcdedit /enum active
    bcdedit /set {GUID} PATH \chain0
    when i did this it didn’t give me a GUID number under Mac OS X. instead there were 2 different GUIDS and i picked the one that was most likely the Mac OS X one, which i got it right. so i finished this. anyways i got almost everything working. the dual boot screen comes up too and shows vista and mac os X. i tried to boot into Mac OS X though and it gave me “chain booting error”. i don’t know what to do to get mac os X working. i’m pretty sure i got everything right in following the guide. i’ve done this about 3 times over(wiping the partition out each time before trying again though) and i always get “chain booting error”. What should i do to get OS X up and running? Oh, and i deleted the OS X partition for now, and took it out of the booting entry so my computer just boots into vista now. so whenever i get info on how to get mac OS X to work with the dual boot, then i’ll install it again. any help?

    just thought i’d tell you… i had that happen before once too. You probably entered the windows GUID number when you were setting up the dual boot. just go into the command prompt and do “bcdedit” and it should list what you have. if you have 2 of the same GUID then enter “bcdedit /delete {GUID}” (GUID being the number). You might need to delete the OS X partition first to get your windows boot loader to just boot into vista. Then reinstall mac os X like you did before, and when it comes to setting up the dual boot setup, do like you did before except put in the Mac OS X GUID. when you restart there should be 2 options… 1 to boot into windows, the other to boot into OS X. good luck getting OS X to boot though. i did like the guide said and i’m getting “chain booting error”. something to do with vista boot loader not recognizing OS X as a bootable partition i think. i don’t know what to do about that though

    I did every thing and then when i go to the OS
    selector i select the Mac OS X and then follow
    the instruction but then it shows the Apple
    icon and then automattically restarts PLZ HELP

    Every time after I typed ‘-v’ and press enter then there have short, five lines of scrolling text on the screen then restarted automatically… It kept restart before enter the OSX setup. What should I do to solve this issue? Thanks!

    Try to Load which iatkos install disk, and do the darwin boot steps again, works for me.

    Yes I was using iATKOS v1.0 on DVD. I have follow everything exactly as what it said above till the point to entering the OS installment, it kept restart automatically after I type in “-V”. The DVD is works like I pressed ‘F8’ when it start 8 seconds counting. I have also tried just press ‘enter’ to install instead press ‘F8’ and it just restarts automatically without completed anything… Thanks for the quick response!

    i got a “still waiting for root device” message about 6 times at annoyingly slow rates. im guessing that would of ended at root device not responding


    Waiting for root device means you have non-conpatiable hardware.

    Try using the commmand cpus=1 at the boot menu after hitting F8

    Hi! I installed ToH 10.5 Leo and it worked. It doesn’t have Darwin boot under utilities so I didn’t install it. When I boot my PC I choose Mac …. and the screen becomes black, after a few seconds it returns to the main boot screen. Where is my problem, please?

    I dont seem to find the file the dvd am using seems to be encrypted

    i am using the kalyway 10.5.2 am not sure if it applies?

    How to uninstall it?

    hmm… it still won’t boot from the dvd and hangs at “still waiting for root device” i tried using “-v cpus=1” at the boot prompt and it still wont work.

    I have read that this issue can be fixed with and external dvd rom drive connected through the usb. Can someone verify this and let me know.

    the OSX disk wont support the nForce SATA drivers, only PATA. try an IDE harddrive

    After pressing F8 and either typing -v or -v cpus=1 is see an error about FireWire being set to full-secure and then the following text:

    MACH Reboot

    This is followed by the PC rebooting. Can anyone help me? 🙂

    Hi there! Nice tut! Just wondering, is it the same to download the iAtkos v1.0i, iAtkos v1.0ir2, iAtkos v1.0ir3 or the iAtkos v2.0i? Which one should I install?
    I’ve got an HP Pavilion dv6379us, Intel Core 2 , T7200, 2.00GHz with 2GB RAM.
    Please, just throw me a few lines.

    @sebas go with iatkos v2.0i it’s the newest one and it has the most patches.

    @betzster thanks, i’m downloading that one, but meanwhile i started with the installation of the iAtkos v1.0r3. everything went fine until i got to the part when i had to format my new partition. i opened the Disk Utility, and guess what? there were no drives! it was like i had no HDD! plz drop me a few lines, thanks.

    very nice guide.
    my only problem is that my keyboard does not work once the installation process begins. any clue?

    Hello, I did “Press F8 as the countdown begins and type -v at the prompt and hit enter”, and then I see scrolling text on the screen, but soon it stops, the stuff I see is “NO such file or directory” and unknown SIGSEGV code 0, then it doesnot go any further, please help, thank you very much

    First off, thanks for the great guide!

    That having been said, I am a little stuck. I finally properly shrunk my drive using the Vista utility, and have a 9.5 gig partition unallocated. Unfortunately, this partition doesn’t show up in the Mac OS X disc utility. I have partition 1 (the restore partition for my computer) partition 2 (the main vista partition) and then nothing. Each has the correct size (after the unallocated partition was created) but I can’t see the unallocated partition! Any suggestions?

    Can I use iAtkos v2.0 instead of v1.0, because I can’t find a good v1.0 download?


    […] 4. Dualboot Windows Vista and Leopard 10.5.1 (Intel only) […]

    I have a question about it:
    I’ve followed your steps and everything goes good, but when the installation prepares I’ve have to select in the Disk Utility a drive where I want to instal it but it can’t find any drives :(. Please help; thanks

    your step by step worked just fine for my hp laptop. But v1.0 doesn´t run very well on my dv9730. it runs very jumpy. I was wondering if you know how to do this same thing with iatkos v2.0. I have tried following the same instructions for v2.0 but it doesn´t work. I get kernal panic while its booting up in the grey screen with the apple logo. Maybe the steps would have to be different. Thanks

    Hi, i am trying to install iATKOS 1.0i but installation get stuck when i have to choose the hard disk. There is no hard disk showing and also, there is no Disk Utility in Utilities menu.

    Please help !

    Hey thanks for the guide but do i have to do a clean install of vista or can i just partition the harddrive with the vista i already have installed

    i already have a dual boot of vista and ubuntu installed using the vista bootloader (with the help of EasyBCD) and i was wondering if id just follow these instructions and then at Leopard in EasyBCD, or if this would mess up my ubuntu boot

    (vista takes up one drive, and i was planning on installing leopard on the same drive as ubuntu)

    When the “scrolling text was suppose to appear it stalled at loading HFS+ file: [System/Library/Extensions.mkext] from 4230450 then after about 20 seconds it displayed and repeated EBIOS read error something about media and repeated it 3 times, it then went to another screen saying bsd process name corresponding to current thread: unknown, mac os verson: not known yet, Kernal version: darwin kernel version 9.1.0: date made by so and so and so what do i need to do to resolve this?

    Cool. Thanks!, This guide works!

    Gust A Notice… iATKOS v2.0i is out! Its much better and squashes most bugs!
    Get it from any torrent

    does this also work with iAtkos v2.0i ?

    Hi… I downloaded the iATKOS V4i and also verified that the MD5 checksum is correct… Now, when i boot up from the DVD, i get the Darwin boot loader and after that, the white/gray background with the Apple Logo on it… The problem is, after a while i get a small “Not allowed” symbol in front of the apple logo (a small white circle with a slash scross it, like the ghost buster icon).. all this while there is small spinning “wait sign” running at the bottom… even after waiting for a long time, the screen does not progress to the next one… just remains at that white/gray bg with apple logo and the small not allowed symbol on top of it…

    The following are my system specs:

    System Manufacturer: INTEL
    System Model:DG33FB
    System Type: X86-based PC
    Processor: Intel(R) Core(TM)2 Duo CPU E6850 @ 3.00GHz, 2997 Mhz, 2 Core(s), 2 Logical Processor(s)

    Total Physical Memory: 2,037.01 MB

    Is there some setting i need to adjust (like in my BIOS)? Please help as I am completely new to this thing….


    after installation, I try to boot vista with the dvd drive empty, and it says hfs+ partition error. can i somehow bypass this to get back into vista, because i really need some stuff on there. Thanks alot

    Your keyboard hardware may not be detected by iAtkos.. I recommend you contact the official iAtkos team at their forums.
    iAtkos rarely works on hardware, the problem is compatibility (I have a website all about the latest software and technology. believe me, I know.). If it does work then your damn lucky.

    That goes for everyone having some sort of problem (google iatkos official forum) search for the forum and ask the software creators theyre selfs. I only helped with the coding, the hardware is not my strong point.

    If your having a problem with your BIOS (or you think you are) then check out YOUTUBE.com there is a lot of vids related to iAtkos and they might help you out ;-)!

    Thanks and sorry I can’t help MReda.

    P.S. I have been having problems downloading iAtkos v4i. If someone can post it to me or if we can work something out then it would be much appreciated! (bogus internet!)

    By the way…. You can always Format your PC, install iAtkos (if you can) and then use Apple Bootcamp to Install Vista/XP (i’m not sure if you can install vista with Bootcamp) but try apples website. Search for Bootcamp and install or whatever.

    People who had problems with mouse or keyboord may be you are using PS2 devices try to use a USB.

    Worked for me ok?! Thanks

    sorry i have the mac os mac-os-x-10 4-tiger-on-disk-image-with-pear-pc-sak so i burn’t on dvd 8.5 gb and its done .i put this dvd in my dvdrom and i open it on the vista windows but i found nothing in the and in the same time i look to back of the dvd i see that its full :S i cant understand , may the vista doesn’t see the mac files or what

    I am able to get to the boot screen where I can choose either Vista or OS X. When I choose OS X, I can then select NTFS or OS X. I select that and it looks like its going to boot into Leopard then it reboots my computer. This happens every time. Lil help….

    After reading that TimeMachine will not work in this environment, I wonder if it is worth the effort. Anyone have TimeMachine working?

    hi, I successfully installed leopard but after it boots, it boots directly to vista and i have no idea how to boot to leopard can anyone help pls?


    there is just one thing to add. After creating a new volume in Windows, “Disk Utility” does not recognize the volume. After i have formatted it to FAT32 it works.

    But now everything is working finde on my Sony VAIO SZ2XP, except sound. Now i try to figure out to fix this.

    Thanks for your great guide and keep up the good work.


    I need some urgent help here as I don’t get computer access easily now that my Dell m1530 keeps rebooting right before I see the Vista loading screen. I installed it using the iatkos v4i downloaded from Demonoid. And then I followed through the steps but after the step where I have to flag to 1 then type quit and enter, I instead flagged the HFS and quit. And then it tried to boot in to Mac OSX, but the screen stuck at the grey background with an apple and a spinner wheel. Then I hard shut down the computer and use the iatkos dvd to do the flagging again, this time I flagged the vista partition. So I restarted the computer, but then it goes in to ever restarting without even showing the progress bar where it says Microsoft Corporation.

    I then tried the Vista installation CD but it says that this problem cannot be fixed automatically.

    Please any ideas?

    Thanks a lot for this tutorial!
    Btw. this tutorial works also fine with the iATKOS v4i Version with OS X 10.5.4 =)

    I installed iATKOS v1.0i on my Windows XP Laptop successfully. My laptop is:

    – Intel Core2 Duo 1.66 Ghz
    – RAM 1GB DDR2
    – on 20GB unallocated partition

    The above steps were very helpfull while installing iATKOS. But after the installation the above steps are not compatible with Windows XP.

    As bcedit is not compatible with Windows XP, I add following line to the boot.ini file:
    C:\chain0=”Mac OS X”

    Now when I rebooted, I got two options at boot. One is Windows XP and other is Mac OS X.

    Windows are working fine, but if I click to select Mac OS X at boot screen, it does not do any thing and takes me back to the same boot screen.

    Does anyone from you have ever faced the same situation?
    PLEASE help me on this..

    I am desperate to see the Mac OS that I have installed successfully.

    just hit any key and choose the drive you installed leo on

    then it should boot w/o any problems

    Hi. I installed iATKOS v1.0, did it according to the guide. I read somewhere above, someone had the same problem, but fixed it and didnt say how he fixed it. After reboot, I select the OS, I pick OSX, but it still boots into Vista. How do I fix that? Thanks

    I can’t go to the installation at all the dvd just boot and I got nothing out there…then it reboot again…
    I already tried to use the -v command but I got nothing >.<

    I followed all steps.
    When restarted, I got message “CHAIN BOOTING ERROR”

    it stops on the screen after this step “Press F8 as the countdown begins and type -v at the prompt and hit enter.” has text on the screen and says only one style help me cause i waited for 4 hours nothing happened.

    it stops and the text is flow control is disabled

    It supports multi-hard drives.
    FOr the guide, replace anymention of chain0 with tboot.
    to get tboot, google.
    THe like I found was dead, so I am waiting for a new one.

    Not all hardware is supported. Check this out: uphuck.com

    Ask them for assistance, I’m going to be hanging around at my site… blackslash.net

    I got vista, mac and linux on my computer. And its SSE2!!! They said iAtkos v4i does not support it. How come I got it working? lol.

    Sir, i got a DVD of iATKOS_v4i__10_5_4..
    when i boot with the DVD the loader says to press anykey or the F8 thing..i pressed -v and then it started loading but it freezes up and the screen shows somethings like Security system loaded and all..
    the last lines are –
    Darwin OS86……….

    If i do not go with the continue thing it says me to restart my PC..

    Could u please help me what to do now..
    Thanks n advance


    thanks for all your good work !

    the problem i seem to have is the same as
    @chandra bhushan.
    not recognizing my unallocated part on the hd, and unable to format an other type of partition, but you kind of mentioned that. just thought to try anyway, cause the other way didn’t work either.

    unfortunatly the link you supplied strangely doesn’t work fdor me.
    some sort of error on the page
    (used firefox ofcoure) reluctantly i tried IE but didn’t work either.

    what can I do to fix this partitioning problem?

    Trying to install iATKOS Leopard OSx86 10.5.1 v1.0i on a Dell Vostro 400. I try to boot from CD and used various switches [-v] [-v -x] but it won’t start. I am getting this error: “system config file ‘systemConfiguration/com.apple.Boot.plist’ not found

    any ideas?

    Thanks for that guide. Bu i cannot boot into mac. It says “chain booting error”. What should i do?

    Hey, thanks for the set up, I am so close and feel bad for asking the same question but I can’t get past the chain boot error. Thanks for the help

    do u have a guide for iatkos v1.0i R2?
    I have vista but processor is sse2 and last time I installed the booloader wouldn’t show up, thanks.

    didnt work for me as soon as i tried to load up the disc it starts then just reboots my computer.

    “Now restart the machine and boot into the Leopard DVD that you burned using the iATKOS v1.0 DVD Image.”

    I’ve just got one quick question: Do you need a Mac keyboard and mouse for this to work, and if so, when should you switch from the pc keyboard/mouse to the mac ones during this install process?

    the scrolling text stops, and after every minute or so it says “still waiting for root device”.

    nice guide. Is there a way to install windows after iAtkos is taking up full hd? (resize, install, then use a boot manager?)
    Somehow I doubt its that simple… thnks again

    my computer gets stuck saying still waiting on root device when i try to install mac -_- any help guys?

    Everything worked except either i messed up on the boot loader or it messed up but everytime i click mas os X it goes to vista so both of my partions are vista. Need more help on how to dual boot with mac and vista after the installation of mac.

    hi firstly tnx for all inf,
    well i followed all what you sayed
    but the installation stop every time at the gray screen with the apple signal that’s all… plz can you help me

    I followed it with 2.0i and still when I select mac osx partition I get an error. Any help would be appreciated.

    Hello, what if System Repair doesn’t fix the problem with “winload.exe”? What if after system repair there is an error which says “HFS + Partition error”?


    If it stops anywhere then drop a comment and I’ll try to help you out.
    – – – – – – – – – – – – – – – – – –
    I have this problem. How can I solve it?

    hello! thanks for the detailed install guide, but somehow i got into some problem.

    after hitting F8 and typed -v on the prompt, i get the scrolling texts and installation stops to respond with the last line on the scrolling text reading as:

    MAC Framework successfully initialized using 16384 buffer headers and 4096 cluster IO buffer headers
    Extension “com.apple.driver.ACPI_SMC_PlatformPlugin” has immediate dependencies…; use only one style”

    How should i go about it? thanks in advance!

    i get a problem when after the “-v” step. It stopped when it came to the firewire step, and it said that it resolved to all-safe or all-secure mode. So yeah, thank you for all of this. Any help will be GREAT.

    motherboard: ga-ep45-ds3l
    e4600: CPU
    I’ve installed Vista 64 bit and everything is working well but I would like to set up a dual boot with Leopard (I’ve purchased 10.5.4).

    LG GH22ls30: DVD burner
    WD7k32m sata2: harddrive
    2Gx2 cors twin2x4096: ram
    Palit NE/860ts: Vidio card
    netgear GA311: ethernet adapter


    I followed the guide and installed iATKOS 5i on a Sony VGN-C2S laptop together with Vista but I have difficulties to map the entry in the vista boot menue to the corresponding partition. This is the current reaqding from EasyBCD:

    There are a total of 3 entries listed in the bootloader.

    Default: Microsoft Windows Vista
    Timeout: 30 seconds.
    Boot Drive: C:\

    Entry #1
    Name: Windows 7
    BCD ID: {c8ef6821-dd4c-11dd-b3ee-cb04bd258ea8}
    Device: \Device\HarddiskVolume3
    Bootloader Path: \chain0

    Entry #2
    Name: Microsoft Windows Vista
    BCD ID: {current}
    Drive: C:\
    Bootloader Path: \Windows\system32\winload.exe

    Entry #3
    Name: Mac OS X
    BCD ID: {c8ef6824-dd4c-11dd-b3ee-cb04bd258ea8}
    Drive: C:\
    Bootloader Path: \chain0

    I can boot into Vista, but not into MacOS using the Windows 7 entry. Please advice.#


    I have installed boot loader into my OSX Partition, installed OSX and have the dual boot screen, but I cant get teh last command “bcdedit /set {GUID} PATH \chain0” to be recognized, so I know thats where my errors are occurring. I’m on my 23rd install of this over a weeks time and have waited to ask for help thinking I was just missing something in my handling of writing the code. I’m running an Inspiron 1318 with an Intel Dual Core processor and 4 gb or ram. So far up until that one line of code mentioned above everything has worked like a dream. Any ideas on what I’m screwing up?

    Okay, I got past the code issue and was able to actually boot into Leopard, gets to the White screen with the apple logo, runs for a bit and hangs… anyone have any ideas?

    I’ve had the Root device not responding error for about 3 years.

    Even on different PC’s…

    Then the other day i solved the problem – I bought a new SATA DVD drive and it installed perfectly.

    For $20 you can fix the problem! Get one!

    I followed the guide, half of the HDD for Vista and half for Mac, but was not able to setup a boot option at first and start the computer in any OS.

    I then re-installed Vista. It shows me only one partition :C, the partition for MAC being invisible. I can see it though if I use Disk management.

    If I start from the MAC DVD, I can also see the 2 partitions, one is :C and the other I called MAC.

    I redid the bcdedit commands which gave me the dual option at start-up. When I choose Vista, I boot with no problems. When I choose Mac OS X, the dual screen comes back again. I pressed the F8 key, selected the partition for Mac and pressed Enter as indicated in the guide, but I still can’t boot in Mac.

    What should I do?

    Hy, i have install it,i have dual boot… i select mac , select drive an tre pc restart

    Hi to all that have “CHAIN BOOTING ERROR”.
    I think I found a solution for this unpleasant error. In the manual, when it says “# Now Close Disk Utility and Select Utilities -> Darwin Boot. Type Y at the prompt.
    # At the prompt when it asks for the Disk Number enter 0. For the Partition Number if your Leopard Partition is 2nd on the disk, then enter 2 and so on.” for the Disk Number I choose 1 instead of 0 (my only HDD). So now I can boot into Leo.
    Still some instalation problems, but I hope fixable.
    Hope this helps

    Please help mine hets stuck after I put -v and then it stucks at

    Darwin Kernel Version 9.1.0: Sat Nov 17 02:56:34 SCT 2007: made bye TolT: xnu-1228.0.2-1/Build/obj/RELEASE_I386

    YOU ARE AWESOME! thank you so much!

    The Terminal window is a good substitute when “Darwin Boot” option is not present. Use fdisk like so to flag the partition you are installing OS X onto:

    fdisk -e /dev/rdisk0
    flag x (1, 2, etc)

    Also: A new NTFS partition created with Windows Disk Management and then reformatted to HFS+ with the OS X installer’s Disk Utility will work just fine. If your install cannot read the “Unallocated Space” use this method.

    install went flawless but when i got into the terminal and typed -s it said unknown command. ande when i tried typing fdisk -e/dev/rdisk0 i said cylinder argument out of reach… any easy solution?

    Hi, thanks for posting the guide, however, i was not able to load os x on my eee pc 1000h laptop.

    i tried using -v, -s, after it shows a bunch of message it gets stuck to “apple.kpi components; use only one style”. so what i did, i tried to use -x and -f, what will happen, it will go to a screen where it shows you an apple logo with circling progress under it, then it’s stuck there not doing anything but to circle and circle and circle… i waited at least an hour, but it’s still not changing to a different screen.

    Amd athlon 64×2 dual core processor 4200+
    my pc support SSE2.
    my hardrive:400GB
    since i already had vista installed,
    i just went to disk management to create
    another partition for Mac os of 175GB.
    was able to boot from my Leopard 10.5.1 dvd,
    when i arrive at the installation page,i went to disk utilities
    choose the partition i wanted to install onto.
    clicked on erase, choose extendet journal
    then erase, hoping it will partition my hardware.
    it just stood there erasing for ages, i waited for like
    15 minutes and still haven’t partitioned anything.
    i just turned my power off,please help
    i really need this to work out.

    i have been trying this for ages,and still its not working.
    i tried jas 10.4.8 aswell, the problem with that is, it

    leopard, cos it can find my hardrives, almost thought that was it.
    i will appreciate your help.

    Hey I tried to install Leopard on my computer and after the scrolling text it froze like halfway down. It stopped and the last entry that it says is:

    I have a preinstalled Vista and already installed linux OpenSuSE 11.1.
    Now I want to remove linux and install MAc OS X darwin .
    I would like to know if the same procedure would work in this case.

    followed this exactly with a Dell Inspiron 1720.
    worked flawlessly!

    just the part about the BCDEdit part was confusing. Make sure the brackets for GUID kept there.

    You know, It was a bit confusing for me. I have an ISO file in my folder with the mac install disc in it. All i wanted to do was install that as a virtual machine. But i couldnt find a virtual machine program with MAC OS X suppout in it. PLease tell me how to do it FREE! (No scripts please) 😉

    I have a question. In the step “Boot into Vista. Copy the chain0 file from the Leopard DVD to C:” So I just copy the chain0 file located in the iATKOS dvd and copy it directly to the C: drive and and not in any folder right? Sorry. I’m new to this.

    Hi i got up to the step where i was in disk utility then closed it then go to utilities to darwin boot loader..thing is there was no darwin..only chameleon and some pc one which i continued to install osx and then it went to the grey screen and stayed on it after then giving me a zero with a strike through it..Now it wont boot in vista when i choose which drive to boot from it says its not there or sumthing would i like to restart and all it does if i leave it is go to the apple screen..i hope i havent damaged anything..it seems like vista has disappeared… hellppppp

    Yup mine stopped. it has mac OS version:
    Not Set yet

    hey, on the 5th bullet under steps (above) i get about 5 or 6 lines of text then my screen goes white for a moment. after that the screen goes black and does nothing. (even after 30 min!) i followed the instructions exactly as said.

    i have a toshiba l300d laptop running vista home premium sp2, 1gb of ram, 1.90 GHz AMD Athlon 62 X2 dual-core prosser.

    please help. you can e-mail me info at
    (austen.holland@live.ca) without brackets.

    in my opinion i think that if you have a AMD processor you can not install mac as mac does not support AMD.

    Yes that is normally true, but are there any patches available to make AMD computers work with this method/guide? If there is none (search Google and other engines) that’s okay. Thanks.

    I did everything like I was suppose to. I can’t edit my bios setup crap. I have no options to really do anything but change system time and other simple stuff like that. I don’t know what to so. When it gets to the black load up screen it say waiting on root device. Help anyone? Got a hp pavilion slimline with a amd 64 live

    if you do not have any “boot” options in your BIOS then your computer most likely has pins on the motherboard that make those changes.

    you can get a patch for AMD that will allow you to use mac on pc but when i tried it, it still did not work for me.
