I had a similar situation I think.  After an install boot would stop
at -
"Using Drive: 0 Partition: 3"  I could boot into the new install off
the boot floppy with -
>boot hd0a:/bsd

What I did was boot with a windows 95 floppy and -
fdisk /mbr

I got this off the mailing list archives.

This may or may not be exactly what your experiencing so use this
info at your own risk.
