I am gonna keep my current drive for xp , however i have ordered another hard drive and 4 ore gigs or memory for windows 7 64bit. Problem is i dont know what to do, i once used 98se,and xp on diferent drives and when the computer started it gave me the option to start in one or the other, so i want to do that again, so i wont have to run a second tower, anyone know how i can do this?
