Booting XP and Mac OSX86 togheter [howto]

September 12th, 2009 | Posted by deCoder in Life Hacks

I’m assuming that you installed Windows XP on 1st disk and the OSX86 on a separate disk (2nd disk)

Here we go…

Getting the chain0 file from your OSX86
- Put a memory stick in the PC and boot OSX86
- In OSX86 start terminal and type:
cp /usr/standalone/i386/chain0 /Volumes/[MemoryStickName]/

chain0 is a 512 bytes file containing the Darwin boot sector

Placing the chain0 file to the root of your XP boot partition
- Reboot to Windows XP
- Be sure to copy the chain0 file from the memory stick to root of the Windows XP boot partition (usually C:\)

Editing boot.ini file
- Click-Right on My Computer, then Properties, Advanced, Start Up and Recovery and then Settings
- In the Startup and Recovery page, press the Edit button
- Add the following line to the boot.ini
C:\chain0="Mac OS X"
- Save boot.ini and reboot

On the boot screen you should have another option to boot OSX. Select it and press Enter.

The PC should boot OSX86.
