Well awhile back I installed the iAtkos v5 of OS X 10.5.4 and dual booted OS X and XP. I was dual booting at used Chameleon and was prompted when i started the computer up which operating system I wanted to use. OS X ran perfect and I had it perfected the way i wanted. Soon after XP got corrupted and instead of fixing it I chose to install Vista Ultimate. I still have OS X on the other partition and haven't been able to boot to it since the install of Vista. Is there easy way to get my dual boot fixed so that I can go back and use my OS X?

Yea, the chain0 method. I'll post a write-up shortly.

 

 

Edit: Ok, you can either get the either get the chain0 file from your OSx86 install DVD or download it from here http://wiki.osx86project.org/wiki/index.php/Chain0 where it says "Alternatively, get just the chain0 from here: riccardo.raneri.it." Put the chain0 file in your C: directory.

 

The easiest way (to me) is to use EasyBCD ( http://neosmart.net/dl.php?id=1 ) to add Mac OS X to the Vista Bootloader, then change the boot path because EasyBCD sets it to nst.mbr or something. Soooo, download EasyBCD and where it says Add/Remove Entries, Add one for Mac OS X (x86). Then run Command Prompt (start->run->cmd) and type in bcdedit /enum and it should show you the entries. Now, you'll need the BCD ID of the Mac OS X partition. It should be in brackets like this {ID-blah-blah-blah}. If id doesn't show you in cmd, look on EasyBCD, and you should see "Display Mode" on the screen that lists the entries. Click Detailed (Debug Mode) and it should show you the BCD ID. Something like {b3009909-aca0-090-099909} with different letters/numbers of course. Now, copy that, and go back to Command Prompt and type "BCDEDIT /set {b3009909-aca0-090-099909} PATH \chain0" without quotations and of course replacing {b3009909-aca0-090-099909} with your BCD ID. Press Enter. It should say Entry Successfully edited or something of the sort. I just typed all of this from memory so bear with me. After that, you should be good to go. Let me know if you need any help.

I used the chain0 method with XP. i went into the boot.ini file and followed some steps and added something to make it appear when I booted the computer. Only thing was, I had to go into the BIOS and set it to ACHP or something so that the OS X side would work. Will I still need to do this each time before I can use OS X and Vista? Or is Vista diff?

How exactly do I add the OS X bootloader to Vista? Do i click on manage existing entries, and click my Windows Vista, then at the bottom click MAC tab and name it Mac OS X. then click add entry? Then go into the cmd and do the edit with the id number and i should be all set?

 

One more question, If i were to buy another hdd, can I partition it 50/50, 50% for Windows, 50% FAT so that OS X recognizes it? Because I need more room for my OS X files.

First part correct, except you don't have to click on Manage Existing entries; just go to add an entry. Managing Entries is just for deleting or changing the position to be displayed in the bootloader. And I believe the two hard drives being partitioned that way would work. Just make sure to install Windows first.

So after I add the entry go into the cmd and edit like you said, and it should work when I restart?

 

Windows and OS X are installed already. I just meant I wanted to use the hard drive for more room. I know os x uses the fat method, do i need to partition it into 2 partitions so that I can use it for OS X and Vista?

Yea you should be good on restart. And yea I believe you would have to partition it. But then again, aren't most flash drives FAT-32? Meaning you could store Windows and Mac files onto the hard drive without partitioning it. Not totally sure on that one.

I wasnt sure since my Windows XP didn't see the OS X partition but the OS X could see the Windows partition. Guess we'll try and see. I'm out of town at the moment so I should be able to test the computer and see if everything works tonight or tomorrow. And i'll make sure to let you know.

Oh, Mac OS X uses HFS+ file system. It's not seen by Windows natively. But just for a storage drive, if you formatted it as FAT32, I think it would work without having to partition the drive. But only if you're using it for storage. But yea, let me know how it turns out.

Okay, i did as you said and typed it all in and it said it copied it successfully, however it never gave me the option to boot to OS X, it just booted straight to Vista.

 

In EasyBCD your BCD entry for OS X will not be pointing at the OS X boot file location, i.e. Darwin EFI bootloader (which then points to the OS X system)......so, try

 

1. Boot into Vista....go to EasyBCD.....then to Bootloader Management....and choose to "Reinstall Vista Bootloader"

2. In EasyBCD add a new OS X entry
