Tri-Boot Mac OSx with Vista + Ubuntu

Hey, im trying to install Mac with Vista being the original OS, dual booted with Linux Ubuntu. Ive found lots of info that said that Mac can only be run using an emulator, so i found one called PearPC that seams like it will work.

I was just wondering if i need to use the emulator or if i can boot into Mac using the grub loader??

Was also wondering if Vista or Ubuntu will be damaged if i do use the emulator??

Any tips welcome!!

Running OS X on non-Apple hardware is against Apple's EULA, which makes it illegal. Since we don't discuss illegal activity on this forum, this thread is now closed.

Thanks.
