Windows NT could not start because the following are missing or corrupt:
\Winnt\system32\config\SYSTEMware profile/last known good menu.
You can attempt to repair this file by starting Windows NT setup.
NOTE: %systemroot% is the installation directory for Windows NT.
CAUSE
Both the System and System.alt registry files are corrupted or missing.
RESOLUTION
Use the emergency repair disk (ERD) and select "inspect registry files" on
the first menu selection screen. On the second menu selection screen
select "replace SYSTEM configuration." This will replace the damaged System
registry hive in the %systemroot%\System32\Config directory with the
System hive on the ERD.
NOTE: Any system changes made after the ERD was last updated will be lost.

TITLE : Using an Emergency Repair Disk Created by Windows NT
If there is no ERD, a restore from a tape that contains a backup of the
registry will be needed.
If you do not have an ERD or backup tape, you can recover the
System hive by expanding it from the %systemroot%\repair directory using
the following steps:
- Install a parallel copy of Windows NT to an NTTemp directory.
- From a command line prompt, go to the repair directory of the original
Windows NT installation.
For example: CD \winnt\repair - Use Expand.exe to expand the System._ file to System.
- Copy the expanded SYSTEM file to the %systemroot%\System32\Config
directory.
Copy System c:\winnt\system32\config - Try to boot back into the original Windows NT installation.
MORE INFORMATION
During the boot process, if the system hive is corrupted, Windows NT will
try to use Last Known Good by accessing System.alt. If both the System and
System.alt files are corrupted, Windows NT will not be able to boot.
