What specifically is the error - it sounds like you might have a 
corrupt registry, which, depending on the service pack level of XP, 
you might get really lucky and already have a backup on the system you 
can use.

If you can cope with a web page with lots of large LOUD text, try here 
for something I suspect might be of use - having had a couple of 
minutes to look through this now, it's actually one of the better 
guides i've seen, so i'm bookmarking it myself !

You may still need to find someone with an XP disc you can borrow 
though for a while, especially of safe mode doesn't work.
