Hello
maybe not much help But installing XP can be a pain in the a**s and this is because for some reason it does not see devices installed/or it does, but does not like them. ie graphics cards/sound cards etc.
If it were me try and install in dos wipe the hard drive clean then try install XP from CD,
Sorry like I said not much help, but I am not in IT.
I am sure some peeps will give you better advice.
Good luck.
regards
