I recently hit a problem where CHKDSK was running at startup and it would finish, then the computer would restart and it would try to run CHKDSK again. It would do this in an endless loop and never get to the point where you could boot into Windows XP. Luckily I was able to find a workaround.

2. Select the option for Safe Mode with Command Prompt.
3. At the prompt, type chkntfs /x c: and press Enter.
Now restart the computer and see if the problem is resolved. The C drive should be excluded from the scan and should boot right into Windows if the disk drive is still readable.
