I have a Vista RC1 dvd and i was wondering if it was possible to install it to my D drive on my hard drive...i would still have xp pro on the c drive..would it possible to have both and when u turn on the computer select which drive u want to boot off of?

Absolutly... When you go tonsall Vista, just make sure that you target the partition that you want to use. Vista will install it's bootloader and you can choose which OS to use. (Defaults to Vista)

NOTE: I hear it is rather diffucult to remove the bootloader but you should be able to restore XP's by running the Repair Console)
