I am getting the above noting missing or corrupt file. Attempting to boot from the windowns xp CD and am not getting it to work. I have reset the boot sequence to the cd rom. Now keep getting F1, retry boot over and over.
You have a corrupted registry. The repair procedures above are not always successful, then you will need to reinstall XP, but all data will be lost when this is carried out, unless it has have backed up to other media.
