How to Fix a Windows XP Reboot Loop

1. Watch carefully as the computer starts up after a reboot. Select "Recovery Console" from the "Startup Options" list.
2. Install the Windows XP disk into the drive if "Recovery Console" is not listed in "Startup Options." Restart the computer. Follow the prompts and select "Repair" or "Recover."
3. Type the administrator password for the computer.
4. Type "cd system32" without quotes when the command prompt appears. Press "Enter," type "ren kernel32.dll kernel32.old" and press "Enter" again. Type "map" and press "Enter."
5. Type "expand d:\\i386\\kernel32.dl_" and press "Enter." If the Windows XP CD is inserted into a drive other than "D:" replace "D:" with the proper drive letter.
6. Type "exit" and press the "Enter" key. The computer will shut down and reboot again. Remove the Windows XP disk. The reboot loop should now be resolved.
