•  The system was at one time configured with either of the following:

    DRDOS, version that ships with NetWare 5.0
    Novell NetWare 5.0

•  The system is being configured with Windows NT 4.0.
•  The system has the described symptom.

FIX:

The boot drive should be low level formatted before installing NT 4.0.

Note: Low level formatting the drive will delete and remove all data from the drive.

DETAILS:

Novell NetWare 5.0 utilizes DRDOS to create its DOS boot partition.
This leaves the boot partition incompatible with Windows NT 4.0.
