  Howto make a GRUB boot floppy

  linux ubuntu boot floppy document official

  • mount /dev/fd0 /media/floppy  mkdir /media/floppy/boot  mkdir /media/floppy/boot/grub  cd /boot/grub  cp stage1 stage2 /media/floppy/boot/grub

    • When I tird to do these by Ubuntu 'My computer' or xfe I failed (and without correct error messages!). Only the root terminal can do these.

  • then start GRUB in interactive mode by typing grub

    • In root terminal, key in command 'grub'.

  • device (fd0) /dev/fd0  root (fd0)  setup (fd0)  quit

    • I have problem here. 'root (fd0' replies an error says 'unknown partition table signature'. That means the program doesn't know this is a floppy. Try to get help from http://ubuntuforums.org/archive/index.php/t-401455.html

    • Retry key in the command 'root (fd0)' again, ... the problem gone !!
    • 3 more sticky notes...

    • • after the 'quit' , I mount the floppy back and check ... no new file were added. I only seen /boot/grub/stage1 stage2

      • This floppy is really bootable !! It boot up to GRUB command prompt very quickly. I didn't do the above step that copys /boot/grub/menu.lst and device.map. I did it then and the floppy really boot to my Ubuntu 904 from HDD after all although it boots from floppy at first.

      • so, this diskette is suitable for http://a.nnotate.com/docs/2009-05-27/sBK2v0yg/index.html#note34 study
    Add Sticky Note
  • dd if=/dev/hda of=/media/floppy/boot.mbr bs=512 count=1

    • in my case, there's no /dev/hda thus error occured that said so. According to /boot/grub/device.map I got the correct device path /dev/sba and it really works. This command line demos how to save HDD MBR to a file by standard dd command.
