been trying to do it and my ways are not working. i have an old computer used as a file server and i just want to reload windows XP via a keydisk. it updated to SP3 and well didnt reboot. so now i need to do a repair install there is no CDrom in this computer and its a lot of work to just temp hook one up. was thinking this would be the simple way. can someone explain how i can install windows from a keydisk?
