Making a GRUB Boot Disk

It's always worthwhile to have some sort of an emergency boot diskette
for your Linux installation.  Sometimes, however, there is a problem
making a standard emergency boot disk.  However, you can create a GRUB
boot disk.  The following steps are based on material in the "Boot
Methods" chapter in O'Reilly's "Linux in a Nutshell"--AND they work!

The following assumes that you are installing Linux into partition
three on the second disk or, in Linux terms, hdb3.  Obviously, modify
as required.

The steps are as follows:
1. In a terminal window, "su -" to root.
2. Create a GRUB configuration file (/boot/grub/grub.conf) similar to
   the following.  (Note: grub identifies disks and partitions starting
   with zero:  hdb3-->hd1,2.)  The "kernel" and "initrd" lines should
   have the appropriate actual file names from /boot.
    title Red Hat Linux (2.4.18-14)
    root (hd1,2)
    kernel /vmlinuz-2.4.18-14 ro root=LABEL=/ hdc=ide-scsi
    initrd /initrd-2.4.18-14.img
3. Insert a floppy in the floppy drive and create a Linux file system
   on the floppy disk.
		mk2fs /dev/fd0
4. Mount the floppy drive and create the directory /boot/grub.
		mount /dev/fd0 /mnt/floppy
		mkdir -p /mnt/floppy/boot/floppy
6. Copy the grub.conf, stage1, and stage2 files from /boot/grub to
   		/mnt/floppy/boot/grub.
7. Run the grub command as shown below.
		grub --batch <<EOT
		root (fd0)
		setup (fd0)
		quit
		EOT

You can now use the floppy disk to boot to your GRUB menu.
