Issue
On
a system that has at least two OSes, Windows NT in a NTFS partition,
and Windows 2000 /XP/2003/Vista (FAT or NTFS), when running Windows non-NT Windows,
all NTFS partitions on the system are converted from NTFS 1.2 to
the newer NTFS 3.0 or 5.0 file system.
Windows NT
4.0 SP3 or older
If you are using NT 4.0 SP3 or older, Windows NT will no longer
boot. This occurs since Windows NT SP3 and older does not understand
the NTFS 3.0 file system. The NT partition's data can still be accessed
from Windows 2000/XP/Vista. The only way to change this back is a special feature in our Partition Commaner 10 that down-coverts NTFS partitions.
By default
System Commander 7 (but not older versions) will use super-hiding
to help prevent a newer 2000/XP/Vista from changing the NTFS file system.
Windows NT
4.0 SP4 or later
In this case, Windows NT has some understanding of NTFS 3.0
(converted from Windows 2000), and should boot and run normally.
The tools in Windows NT (all service packs) for disk maintenance
and diagnostics, such as CHECKDSK do not understand NTFS 3.0 and
will refuse to run. You can boot into Windows 2000 and run its newer
disk utilities on the NT partition.
If you run Windows XP/Vista, all NT versions do not understand the new
NTFS 5 format and will no longer run. The only way to change this back is a special feature in our Partition Commaner 10 that down-coverts NTFS partitions. By default System Commander 7 (but not older
versions) will use super-hiding to help prevent a newer 2000/XP
from changing the NTFS file system.
Recommendations
If you wish to have both Windows NT and Windows 2000/XP/Vista on
the same system, we recommend using only a FAT or FAT32 partition
for
Windows NT. VCOM's current tools, such Partition Commander include a converter to make a NTFS partition
into a FAT or FAT32 partition. If this is done BEFORE Windows 2000/XP/Vista
is installed, the Windows NT should work fine with later Windows in another partition. It may also be possible to convert
a Windows NT NTFS partition to FAT/FAT32 after Windows 2000 has
modified
it, and still have NT boot properly, but this has not been tested.
