I had a computer that the owner said had a virus on it and wouldn't start up, so I decided to use an XP cd to do a repair install to get the computer running without deleting the files. As it turned out, in the middle of the setup it asked for the cd key. I used the key found on the tag (wouldn't work) and used the key on the CD (Which is a volume license version) (wouldn't work).
Now I'm stuck. I can't go back and cancel the install. It won't let me use another XP CD (it wants the original CD that I started the repair with) and I don't know how to delete the temp install files. I put the Drive in another computer and backed up some files, but would like to take another route to fix windows.
