On windows NT 4.0, I can't be of much help, since I do not have a box with NT installed. But even if I had one, my knowledge of NT would be far from adequate to help you with that. On FreeBSD, where my disk is separated in 4 primary slices (what the DOS world calls partitions), it's as simple as doing: # mount -t msdos /dev/fd0 /mnt # dd if=/dev/rwd0 of=/mnt/rwd0 count=1 bs=512 # dd if=/dev/rwd0s1 of=/mnt/rwd0s1 count=1 bs=512 # dd if=/dev/rwd0s2 of=/mnt/rwd0s2 count=1 bs=512 # dd if=/dev/rwd0s3 of=/mnt/rwd0s3 count=1 bs=512 # dd if=/dev/rwd0s4 of=/mnt/rwd0s4 count=1 bs=512 Then, if the disk gets screwed up during installation, I usually boot with a bootable cdrom and restore these by swapping if= and of= parts of the command line(s). -- Giorgos Keramidas, <keramida@ceid.upatras.gr> "What we have to learn to do, we learn by doing."
