If GRUB was not installed during the installation process, it can be
installed afterward. Once installed, it automatically becomes the
default boot loader.
Before installing GRUB, make sure to use the latest GRUB package
available or use the GRUB package from the installation CD-ROMs. For
instructions on installing packages, refer to the chapter titled
Package Management with RPM in the
Red Hat Enterprise Linux System Administration Guide.
Once the GRUB package is installed, open a root shell prompt and run the
command /sbin/grub-install
<location>, where
<location> is the location that the
GRUB Stage 1 boot loader should be installed. For example, the following
command installs GRUB to the MBR of the master IDE device on the primary
IDE bus:
/sbin/grub-install /dev/hda |
The next time the system boots, the GRUB graphical boot loader menu
appears before the kernel loads into memory.
