In many cases, the GRUB boot loader can mistakenly be deleted, corrupted, or replaced. The following steps detail the process on how GRUB is reinstalled on the master boot record:
- Boot the system from an installation boot medium.
- Type linux rescue at the installation boot prompt to enter the rescue environment.
- Type chroot /mnt/sysimage to mount the root partition.
- Type /sbin/grub-install /dev/sda to reinstall the GRUB boot loader, where /dev/sda is the boot partition.
- Review the /boot/grub/grub.conf file, as additional entries may be needed for GRUB to control additional operating systems.
- Reboot the system.
