What I would do is boot the linux rescue floppy and get to a shell and
fdisk from there to set up your partitions.  Once you've done that, do a
dd if=/dev/zero of=/dev/hd?? bs=1024 count=1
then reboot, with a dos boot floppy, execute fdisk /mbr, format each dos
partition with the /s option (format c: /s).  The reason for the dd line
is dos for some reason requires 5?? bytes of zeros at the beginning of its
partition.  Rather than look up the number (I'm pretty sure it's not
something sensible like 512) I just suggested 1024 bytes of zeros.  It
wants this before it will recognize the partition as it's own and sys it.

good luck.
