You must be joking, nobody can be of any assistance. To do so would be sheer piracy. I doubt if you will get any takers here, we are all angels when it comes to this sort of thing. Anyway your product key would not work with another copy, and anyone who did would compromise their own installation. How did XP Pro become installed without a disc. That looks to be a dodgy installation as well.
Only two choices. Go out and buy a RETAIL copy of XP Home, or repair it yourself.
