After you receive this error message, Windows does not start.
This issue may be caused by a damaged NTLDR file.
To resolve this issue, replace the NTLDR file by using the Windows Recovery Console:
Restart your computer by using either the Windows 2000 CD-ROM or Windows Setup floppy disks.
At the Welcome to Setup screen, press R to repair the Windows 2000 installation.
Press C to repair the Windows 2000 installation by using the Recovery Console.
Type the number of the Windows installation that you want to repair, and then press ENTER.
Type the administrator password, and then press ENTER.
NOTE: The Recovery Console uses the administrator password that you provided when you installed Windows 2000. Changes that you made to the administrator password after you installed Windows do not apply to the Recovery Console.
Type chkdsk /r, and then press ENTER.
Type cd .., and then press ENTER.
Type ren ntldr ntldr.old, and then press ENTER.
Type copy CD-ROMDrive:\i386\ntldr HardDisk:\ntldr, and then press ENTER, where CD-ROMDrive is the CD-ROM drive letter, and HardDisk is the drive letter of your hard disk.
