1) Boot to the LiveCD Desktop (Ubuntu 9.10 or later).

2) Open a terminal by selecting Applications, Accessories, Terminal from the menu bar.

3) Determine the partition with the Ubuntu installation. The fdisk option "-l" is a lowercase "L".

Code: Select all

 sudo fdisk -l
If the user isn't sure of the partition, look for one of the appropriate size or formatting.

Running sudo blkid may provide more information to help locate the proper partition, especially if the partitions are labeled. The device/drive is designated by sdX, with X being the device designation. sda is the first device, sdb is the second, etc. For most users the MBR will be installed to sda, the first drive on their system. The partition is designated by the Y. The first partition is 1, the second is 2. Note the devices and partitions are counted differently.

4) Mount the partition containing the Ubuntu installation.

Code: Select all

sudo mount /dev/sdXY /mnt
Example: sudo mount /dev/sda1 Note: If the user has a separate /boot partition, this must be mounted to /mnt/boot

5) Run the grub-install command as described below. This will reinstall the GRUB 2 files on the mounted partition to the proper location and to the MBR of the designated device.

Code: Select all

sudo grub-install --root-directory=/mnt/ /dev/sdX
Example: sudo grub-install --root-directory=/mnt/ /dev/sda

6) Reboot

7) Refresh the GRUB 2 menu with

Code: Select all

sudo update-grub
