How was this done ?
First need to create 2 partions , one in FAT (to be detected by OSX)
Install OSX Leopard , and Chameleon as boot Loader
After, install Windows 7 , and use EasyBCD to add OSX to the boot.
Then install Linux Mint from Windows using MINT4WIN (find it inside Mind CD/ISO)
You Will have a Triple Boot Machine ! Enjoy
