Im trying to find the best way to dual boot with XP & Vista. I have 3 hard drives. 500GB Packard Bell external. 320GB WD My Book (Was external, but now internal on an IDE cable). 250GB Samsung SATA. I have XP on the 320GB My Book & the Samsung is empty, while all my films, music etc are on the 500GB. Whats the best way to go about this? Install Vista on the Samsung or create a new partition beside XP? The last time i tried to install Vista beside XP i couldnt boot up at all. Any help/advice is appreciated. Cheers
