This article was previously published under Q149180 SYMPTOMS
After you install a service pack on a Windows NT 3.5 or 3.51 computer that
also has Windows NT 4.0 installed, attempting to start Windows NT 4.0 may
result in a failure to load the operating system. The failure may trigger a
momentary error message and cause the system to restart immediately.
CAUSE
The Ntldr file for Windows NT 3.5x is incompatible with Windows NT 4.0. The
installation of the service pack may replace the Ntldr file placed on the
boot drive with a version included with the service pack.
RESOLUTION
To resolve this condition, manually replace the NTLDR file on the boot
drive with the file of same name from the Windows NT 4.0 distribution set.
This version is compatible with both operating systems. If the boot
partition is NTFS, you may need to obtain access to the partition through
the Windows NT 3.5x installation in order to replace the file.
