Can Knoppix be used to install grub in the MBR

[cykick]

Can Knoppix be used to install grub in the MBR for recovery in case of a corrupted MBR, assuming that the same version of grub is also installed in the /boot/grub/ directory of a known boot partition? If yes, what might be the procedure?

[knixkw]

Yes. Start grub. At the grub prompt type (for example):

root (hd2,0)
setup (hd2)
quit

The command root tells grub on which partition /boot/grub can be found. The command setup tells grub where to write the MBR.

After entering root (hd typing <TAB> shows the possible disks.

Good luck

Well first of all....you don't need any partitions marked as bootable. ;) That's a DOS/ntldr thing. Secondly you don't need to have grub already installed.

It's easy. You need to mount your /root partition.

mount /dev/hda1 /mnt/hda1
grub-install --root-partition=/mnt/hda1
chroot /mnt/hda1
update-grub
ctrl+d

voila!
