to answer your question YES *ONE IMPORTANT NOTE VISTA ONLY XP DOESNT WORK XP DOESNT SUPPORT EFI* about a week ago my 250gb hd started to fail so i put an 80gb in and ran just windows on it until i got my new one a nice 500gb hd for my laptop Hope That Helps Mr Puffin
EFI or Extensible Firmware Interface is basicly another version of bios all macs since 2006 use it and some servers use it the reason xp doesnt work single booted is when installing thruogh bootcamp it installs a bios emulator in the efi partition while vista has built in efi support if you want more info on efi Click Here hope that helps
