I am going to buy a new computer. Basicaly what I want is using my old hard drive on a new computer without damage any old information which is already on my old hard drive. If necessary, I don't mind removing the new hard drive from my new computer, and use only my old hard drive, which has Windows XP and lots of data I want to preserve, on my new computer. Both computers are desktop.
How can I do it? Thank you and your advice is solicited.
