After you enter the number for the appropriate Windows installation, Windows will then prompt you to enter the Administrator account password.

Note If you use an incorrect password three times, the Windows Recovery Console closes. Also, if the Security Accounts Manager (SAM) database is missing or damaged, you cannot use the Windows Recovery Console because you cannot have correct authentication. After you enter your password and the Windows Recovery Console starts, type exit to restart the computer.

Type the following command and press Enter.

CD SYSTEM32
(If that does not work, try CHDIR SYSTEM32)
At the prompt type in

Remove the Windows XP CD, type "EXIT" and press ENTER to restart your computer. You should now be able to log on as normal.
