Is the drive damaged, or just the cd ain't working? try and borrow another Win xp cd.
If U don't want to repair install, you NEED to have cd access!!!
because U need to go to Recovery console, use command lines and do a
bootrec /fixmbr, and a /fixboot .
If not, and U have an usb stick to boot from it (only if your bios allows it, and U still need to copy files from xp cd) and U can do a Repair install.
