You should now be able to boot directly into Chameleon, stop the boot countdown and select either Snow Leopard or Windows NTFS as shown in the picture below. Unplug all drives except the dual boot drive and restart.

Write down the IDENTIFIER of your Apple_HFS Snow Leopard drive.

You will have to issue a few commands to Terminal in order to accomplish this task. Therefore, Chameleon loads and you can select either Snow Leopard or Windows 7. You now have to set the Snow Leopard partition so that your computer boots from it first. STEP 4: SET THE OS X PARTITION AS ACTIVE (NOT NECESSARY) UPDATE: The latest MultiBeast will take care of choosing boot0hfs instead of boot0 to automatically boot from hfs partition, even if it's inactive. IBoot + MultiBeast - Install OS X on any Intel-based PC

Unplug all hard drives except this one and reboot.

Under Format: choose Mac OS Extended (Journaled). choose GUID Partition Table, then click OK.

Under Volume Scheme: separate your hard drive into 2 Partitions.

Select your hard drive in the left column.

Open Applications/Utilities/Disk Utility.

Boot into your existing OS X installation.

For now, just know it's installed by default and labeled Partition 1. In a separate guide, I'll show you how to install Chameleon to the EFI partition to leave an OS X install untouched. The EFI partition is a very small (200mb) hidden partition that holds the OS X bootloader and BIOS information on a real Mac. Partition 1 is EFI, Partition 2 will be Snow Leopard and Partition 3 will be Windows 7. When you choose 2 partitions with a GUID Partition Table, OS X will format the drive with 3 partitions. UPDATE: The latest MultiBeast will take care of choosing boot0hfs instead of boot0 to automatically boot from hfs partition, even if it's inactive.įirst thing to do is format and partition the hard drive. You have to manually set the OS X partition active at the end of the process. It's a bit trickier, as the Windows installer will set itself as the active partition automatically.

You can then use Chameleon to select either Snow Leopard or Windows 7 at boot time. The following guide will show you how to put OS X Snow Leopard and Windows 7 on the same hard drive. Boot into Chameleon and choose your Operating System.Move your Chameleon OS X hard drive to top of list.Go to CMOS Setup Utility and choose Advanced BIOS Features.Install multiple operating systems on separate hard drives.It's simple to use a separate hard drive for each operating system. Using Chameleon as your bootloader, you can boot an infinite amount of operating systems on your PC.
