If things do not work as expected, check bootability with a floppy disk.
/dev/hdb1 as your Linux-partition, your
has the following entries:
Run lilo with a diskette inserted. Now try to boot from the diskette.
If your Linux on
/dev/hdb1 can't be
started, the NT OS loader will also fail to start it.
If you see a lot of
01 01 01 01, your root-disk is not accessible.
Check whether all your disks are known by the bios.
If the floppy boots your Linux partition, you can peel of your boot-sector for the NT OS loader with:
# dd if=/dev/fd0 of=/bootsect.lnx bs=512 count=1
You can keep this diskette as your rescue-diskette just in case your Windows NT installation breaks.
