This may not be of much use, but anyway ...
1. Do you have a CD drive on your machine? If so, do the installation via the CD - it should be bootable
2. What is the boot sequence in your BIOS set to?
3. Why would you necessarily want
to use a stiffy diskette to boot with? If you don't have a good reason, then install the bare.i image on the MBR at /dev/hda1 (single boot machine).
If I've missed the mark, I'll shut up now
