After Buying XP Home and Installing it Ive decided that I dont like it that much...I prefer M.E.....so What I did was Installed Me on one 80 gig hard drive and installed XP on a seperate 80 gig Hard drive ...what can I use to boot between the two Hard Drive/OS's?

Mind you I like XP for the stability but it wont run my Games, and my recording software ( Im a Musician)

M.E. on the other hand will run all of my games and music software etc....but it doesnt support files over 4 gig.:>(

Any Help would be greatly appreciated...Thanks in Advance ,Galaxy
