Windows NT Emergency Repair Disk

Using an Emergency Repair Disk

Follow these steps to restore your system using the Windows® NT Emergency Repair Disk. You will need your Emergency Repair Disk, the Windows® NT 4.0 setup diskettes (disks #1-3), and the Windows® NT CD. Beginning with your computer off:

  1. Insert the disk labeled "Windows NT Setup Disk 1", and turn on your computer.
  2. When prompted, insert "Windows NT Setup Disk 2", and press [ENTER].
  3. Press [R] to repair a damaged Windows NT version 4.0 installation.
  4. Setup will display the following choices (all options are selected by default):
    • Inspect registry files
    • Inspect startup environments
    • Verify Windows NT system files
    • Inspect boot sector
  5. Highlight "Continue (perform selected tasks)", and press [ENTER].
  6. Press [ENTER] to allow Setup to detect mass storage devices.
  7. Insert "Windows NT Setup Disk 3" when prompted, and press [ENTER].
  8. Setup will display a list of detected mass storage devices. To specify additional devices not listed press [S], otherwise, press [ENTER].
    Note: A page may be displayed stating that your hard disk has more than 1024 cylinders; this is common with larger hard drives. Press [ENTER] to continue.
  9. On the next screen, press [ENTER] if you have an Emergency Repair Disk.
    Note: pressing [ESC] allows Setup to search for repair information on your hard drive. This is useful when no Emergency Repair Disk is available.
  10. Insert the Emergency Repair Disk into your floppy drive, and press [ENTER].
  11. Setup will then prompt to examine your hard disk(s) for corruption. Press [ENTER] to proceed with disk verification.
  12. Insert your Windows® NT CD, when prompted. Setup will continue with disk verification process.
  13. Setup then displays a list of registry files to be restored (an "'X" indicates that the file is selected).
  14. Select "Continue (perform selected tasks)", and press [ENTER].
  15. Setup will determine which files have been modified, and ask whether to repair these files. To have Setup repair all modified files, press [A].
  16. Once the repair process has completed, Setup will display a message indicated that it is necessary to reboot your computer.
  17. Remove the Windows® NT CD from your CD-ROM drive, any diskette in the floppy drive, and press [ENTER].

The emergency repairs should now be complete.

Note: The Emergency Repair feature may not work if BOOT.INI is missing or corrupted even if NT is installed in the default C:\WINNT directory.
