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:

 The title of the menu item.

 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.

 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).

 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

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/

umount /mnt/system/proc/

umount /mnt/system/boot/

umount /mnt/system/

reboot

13. Reconfigure the bootloader by using tools and documentation from the Linux distribution that

you use. For example, in Debian and Ubuntu, you may need to edit some commented lines in the

/boot/grub/menu.lst file and then run the update-grub script; otherwise, the changes might not

take effect.
