Write TO DVD =
My computer - right click the drive select properties - recording tab - make sure "Enable CD writing on this drive" is ticked.
logging in it gives you two options of wiondows=
they must have reinstalled another version of XP on the drive, Start -run type MSCONFIG prss enter - check the boot.ini tab and click chek drive paths. If both remain delete the version of windows that had the problems. that do again.
If everything copied to seperate drive then sounds as if the drives are set in Raid configuration.
