Re: Roll back an NTFS version?

Did you mean system partition? Be aware that Microsoft defines the boot
partition for the partition where the operating system is installed, while
the system partition is the first primary active partition (where the boot
sector resides)

Try creating a boot disk. For the floppy to successfully boot Windows NT the
disk must contain the "NT" boot sector. Format a diskette (on a Windows NT
machine, not a DOS/Win9x, so the NT boot sector gets written to the floppy),
and copy Windows NT versions of ntldr, ntdetect.com, and boot.ini to it.
Edit the boot.ini to give it a correct ARC path for the machine you wish to
boot. Below is an example of boot.ini. The default is to start the operating
system located on the first partition of the primary or first drive
(drive0). Then drive0 partition 2 and so on.

[boot loader]
timeout=10
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows NT 0,1"
multi(0)disk(0)rdisk(0)partition(2)\WINNT="Windows NT 0,2"
multi(0)disk(0)rdisk(1)partition(1)\WINNT="Windows NT 1,1"
multi(0)disk(0)rdisk(1)partition(2)\WINNT="Windows NT 1,2"

Another possibility is to try loading the controller driver also from
floppy. For the floppy to successfully boot Windows NT the disk must contain
the "NT" boot sector. Format a diskette (on a Windows NT machine, not a
DOS/Win9x, so the "NT" boot sector gets written to the floppy), then copy
ntldr, ntdetect.com, and boot.ini to it. Edit the boot.ini to give it a
correct ARC path for the machine you wish to boot.

In order for this to work you'll want to change the arc path in boot.ini
from multi syntax to scsi syntax to indicate that Windows NT will load a
boot device driver and use that driver to access the boot partition. Then
also copy the correct manufacturer scsi driver to the floppy but renamed to
ntbootdd.sys


Something like this below;

[boot loader]
timeout=10
default=scsi(0)disk(0)rdisk(0)partition(1)\windows
[operating systems]
scsi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows NT 0,1"
scsi(0)disk(0)rdisk(0)partition(2)\WINNT="Windows NT 0,2"
scsi(0)disk(1)rdisk(0)partition(1)\WINNT="Windows NT 1,1"
scsi(0)disk(1)rdisk(0)partition(2)\WINNT="Windows NT 1,2"

What was the original problem?
