SYMPTOMS
If you install a previous version of Windows NT on a computer running
Windows NT 4.0 or Windows 2000, Windows NT 4.0 or Windows 2000 no longer starts, or you may receive one
of the following error messages:
Unexpected Kernel Mode Trap
Windows NT could not start because the following file is missing
or corrupt: \WINNT\SYSTEM32\CONFIG\SYSTEM
CAUSE
On Intel-based computers, the Ntloader file has been replaced with an
earlier version.
On RISC-based computers, the Osloader file has been replaced with an
earlier version.
RESOLUTION
If you are trying to set up dual-boot functionality, install Windows NT
4.0 after you install the previous version of Windows NT.
To resolve this issue, start your computer with the newest version of the Windows NT 4.0 Startup
disks and choose the Correct Boot Files option.
MORE INFORMATION
The Ntloader and Osloader files included with Windows NT 4.0 and Windows 2000 are
compatible with Windows NT 3.51. However, the reverse is not true.
