Thanks alot for the reply, but what if I don't have XP Service Pack? Plus, I should mention that about a year ago I had my PC worked on by a friend of a friend, and he installed XP illegally. When I tried to install a genuine XP that I had, the CD didn't work and I have since lost it. By the way, it says: "The file 'sr.sys' on Windows XP Professional Service Pack 2 CD is needed. Type the path where the file is located, and then click OK."
