Somebody gave me a gateway with windows xp factory installed. I wanted to just take my old hd which is a 80 gig ata 133, windows xp upgrade, and put it in so I wouldn't have to mess around with all my files, firefox favs, emails saved and all that. But it wouldn't boot. I put the old hard drive in as a slave and of course I can access my files once I find them, but not my bookmarks or saved emails. Why? What could I do?
