mount -o bind /dev/ /mnt/system/dev/
4. Save a copy of the GRUB menu file, by running one of the following commands:
cp /mnt/system/boot/grub/menu.lst /mnt/system/boot/grub/menu.lst.backup
or
cp /mnt/system/boot/grub/grub.conf /mnt/system/boot/grub/grub.conf.backup
5. Edit the /mnt/system/boot/grub/menu.lst file (for Debian, Ubuntu, and SUSE Linux
distributions) or the /mnt/system/boot/grub/grub.conf file (for Fedora and Red Hat Enterprise
Linux distributions)—for example, as follows:
vi /mnt/system/boot/grub/menu.lst
6. In the menu.lst file (respectively grub.conf), find the menu item that corresponds to the system
you are recovering. This menu items have the following form:
title Red Hat Enterprise Linux Server (2.6.24.4)
root (hd0,0)
kernel /vmlinuz-2.6.24.4 ro root=/dev/sda2 rhgb quiet
initrd /initrd-2.6.24.4.img
The lines starting with title, root, kernel, and initrd respectively determine:
o The title of the menu item.
o The device on which the Linux kernel is located—typically, this is the boot partition or the
root partition, such as root (hd0,0) in this example.
o The path to the kernel on that device and the root partition—in this example, the path is
/vmlinuz-2.6.24.4 and the root partition is /dev/sda2. You can specify the root partition by
label (such as root=LABEL=/), identifier (in the form root=UUID=some_uuid), or device name
(such as root=/dev/sda2).
o The path to the initrd service on that device.
7. Edit the file /mnt/system/etc/fstab to correct the names of any devices that have changed as a
result of the recovery.
8. Start the GRUB shell by running one of the following commands:
chroot /mnt/system/ /sbin/grub
or
chroot /mnt/system/ /usr/sbin/grub
9. Specify the disk on which GRUB is located—typically, the boot or root partition:
root (hd0,0)
10. Install GRUB. For example, to install GRUB in the master boot record (MBR) of the first disk, run
the following command:
setup (hd0)
11. Exit the GRUB shell:
quit
12. Unmount the mounted file systems and then reboot:
umount /mnt/system/dev/
