Hi I have previously used OSX, Windows 7 x64 and XP x86 (in that order on disk) on my macbook. I use rEFIt as a bootloader. However, I couldn't use the XP installation with parallels. I installed OSX, then XP, then 7 to make it all work. I've now deleted and resized the windows partitions to do a fresh install (needed more space) and before I do, I'd like to set it up so I can run XP from boot for games and in parallels to access my car repair software through mac. I can't have a separate xp for parallels as I need the car software in bootable XP as well for actual repairs with the interface, and it takes up about 20GB. Thanks!
