I want to make a grub boot floppy that is completely self-contained up to the capability to present a prompt and accept and run any grub command (e.g. setup). Can someone please tell me how.- preferably both legacy and new grub2 if different.


This is only for grub legacy. About grub2 I think you should wait till there's something stable.

If you only want a grub floppy and you don't want to make it. Try Super Grub Disk ( http://adrian15.raulete.net/grub/ ). When dded to a floppy and booted just press letter "c" to have a console.

Super Grub Disk is also available as a cdrom.

And it is not a simple Grub Disk. It has a GUI.

How to build your own Grub floppy.

Take a floppy disk (fat or ext2)
Delete its contents
Create /boot/
Create /boot/grub/
Copy from your pc /boot/grub/* to the floppy
Create (if it is not created) a device.map with the following line:
        (fd0)   /dev/floppy
or maybe
        (fd0)   /dev/fd0

I don't know right now which is the most usual device name for the floppy drive.

Run grub from a linux shell.
Type the following commands:
root (fd0)
setup (fd0)

And you're done. You do have the grub floppy.
