Reinstalling the GRUB Boot Loader on Dedicated Server

[AndyD]

Hello All,
Below mentioned are the steps to reinstall a corrupted or mistakenly deleted grub (for RedHat and CentOS systems only) using the rescue mode ::

1> Boot the system from any boot installation medium like a RedHad #1 CD-ROM or a Flash Drive, etc.

2> Use the linux rescue command as shown below at the installation prompt to enter the rescue environment:

linux rescue

3> Type the command below to mount the root partition:

chroot /mnt/sysimage

4> Type the command below to reinstall the GRUB boot loader, where /dev/hda is the boot partition.

/sbin/grub-install /dev/hda

*where /dev/hda is the boot partition

5> Go through the /boot/grub/grub.conf file once again, as additional entries may be needed for GRUB so as to make any custom changes there (like controlling another installed operating system)

Step 6> Finally, reboot the system

NOTE :: Use the above mentioned steps at your own risk
