I made a Grub CD which I intended to use to access various linux OS spread over different partitions (including extended) in the event of a failed MBR or missing Grub on a newly installed OS.

If I interrupt my hard drive MBR Grub, to go to command mode, the "find /boot/vmlinuz" finds vmlinuz on all partitions (including extended) on two drives.

If I interrupt the Grub on the CD, the command "find vmlinuz" cannot find vmlinuz on extended partitions or second drives.

Is this normal? How can you overcome the problem?

How did you make the grub cd?

It was some time ago, and here is the fomular i used.

To make grub floppy:

# cd /usr/share/grub/i386-pc
# dd if=stage1 of=/dev/fd0 bs=512 count=1
1+0 records in
1+0 records out
# dd if=stage2 of=/dev/fd0 bs=512 seek=1
153+1 records in
153+1 records out
#


To make a bootable CD-ROM image, first, make a top directory for the bootable image, say, `iso': $ mkdir iso

Make a directory for GRUB: $ mkdir -p iso/boot/grub

Copy the file `stage2_eltorito': $ cp /usr/lib/grub/i386-pc/stage2_eltorito iso/boot/grub

If desired, make the config file `menu.lst' under `iso/boot/grub' (*note Configuration:, and copy any files and directories for the disc to the directory `iso/'.

Finally, make a ISO9660 image file like this: $ mkisofs -R -b boot/grub/stage2_eltorito -no-emul-boot \ -boot-load-size 4 -boot-info-table -o grub.iso iso

There must be a better way to make the CD now(?).
