Don't know about NT.  But I do use a floppy to boot to 3 different
distributions on /dev/hdb and not of the partitions are marked
bootable.  Here is the script I use to make the boot floppy.

echo "Making Boot floppy for DEBIAN 2.2.3  /dev/hdb10 OK?"
read ans
echo "R-deving /usr/src/linux/arch/i386/boot/bzImage"
echo
rdev -R /usr/src/linux/arch/i386/boot/bzImage 1
rdev /usr/src/linux/arch/i386/boot/bzImage /dev/hdb10
rdev -v /usr/src/linux/arch/i386/boot/bzImage 0x317
echo " Making boot floppy"
echo
dd if=/usr/src/linux/arch/i386/boot/bzImage  of=/dev/fd0 bs=512 conv=sync ; sync

Note that this is for the 2.2.9 kernel (the 0x317) but I have done the
same for 2.0.x kernels as well.

HTH, YMMV, HAND
