I'm afraid I've had to give up on this one. I can't update the BIOS because I can't actually log into Windows, not in any mode, (pretty sure I said this in a previous post...apologies if not), thats why I need to boot off a CD to repair XP. Unfortunately I dont have a bootable USB drive but I don't see how it would make any difference as the other boot options just aren't there, even though they should be.
