     As I understand, this is not possible: diskettes do not contain MBR,
disks do. And these schemes are not interchangeable.

     "fdisk/mbr" just (re)writes MBR booting code, this neither changes nor
deletes anything other (partitions information). And FDISK do not deal with
non-MBR media by definition.

A USB stick can be set up either with or without an MBR.
Windows (AFAIK) transparently deals with either type.
The two computers I have that will boot a USB stick BOTH
insist on it having an MBR to boot from it, and both
automatically detect the USB stick.

You can use Linux commands to switch back and forth.
There is an HP utility which will write an MBR to a
SuperFloppy formatted memory stick (SP27213.exe) under

The Linux command

     mkdosfs /dev/sda (or whatever your device is)

will create a "superfloppy" formatted USB stick.

You can change which way a my USB sticks formatted
with these commands.
