Im a total noob, but i just was wondering if i got another HD and installed the same copy of xp that is on my old HD (version that came with comp) can i choose to boot up with the new HD? If so can i take the files i want to keep from the old HD and transfer them to the new HD and then format old HD and make the old HD an extra storage place or something. I am wanting to do this cause my comp is slowing down and there is a lot of crap that i want to get rid of and i need more space anyway. But i want to put xp on the new HD first and make sure i did it right before i delete xp from the old one and use it a storage. If i can use it like that.
