If there is nothing of importance on the Hard Drive, it might be easier to re-load XP from scratch.
If the system will not alow you to boot from a CD, you will need to download the Flooy boot disks from microsoft click here and run these.
You will need 6 Floppy disks.After running the download, put the first Floppy in A Drive and the XP CD in the CD Drive. Set the machine to boot from A Drive (from Bios or (Usually) F8 on boot up.
Follow on screen instructions. When you get to the BLUE screen (Terms and Conditions), press F8 to accept, then press ESC to get to the advanced mode. Follow the on screen instruction to delete the partition(s)and re-create & Format.
This will then give you a clean machine with no errors.
