I've managed to create a "rescue CD" containing the exact same things as would be on the floppy (script attached). I've got exactly one box running grub, and I want to move it to another bootloader. But, I have zero understanding of how to use the grub rescue floppy, so it hasn't done a lot for me, but YMMV. > Is there some easy way to do the same for a dvd?

I'm sure somebody somewhere knows how to make grub think a CD is a real disk. Ken -- das eine Mal als Tragödie, das andere Mal als Farce
