OK, I asked a question about formating here a little while back, and now I have another question. I am all ready to do it, but there is a problem. I want to use the Windows XP Pro disc for the format, but all I have is a XP Pro upgrade disc. And I don't think I have a XP Home disc, because my laptop came with it pre-programmed. Does the XP Pro disc work, or do I just have to use my quick restore CD?
