C.2.11 Step 11
Step 11: Now that you have chosen which boot loader to install, you can also deter-
mine where you want the boot loader to be installed. You may install the boot loader
in one of two places:
• The master boot record (MBR) — This is the recommended place to install a boot
loader, unless the MBR already starts another operating system loader, such as Sys-
tem Commander.
The MBR is a special area on your storage drive that is automatically loaded by your
computer's BIOS, and is the earliest point at which the boot loader can take control
of the boot process. If you install it in the MBR, when your machine boots, GRUB
presents a boot prompt. You can then boot Red Hat Enterprise Linux or any other
operating system that you have configured the boot loader to boot (see
Figure C-11
on page C-9 ).
• The first sector of your boot partition — This is recommended if you are already
using another boot loader on your system. In this case, your other boot loader takes
control first. You can then configure that boot loader to start GRUB, which then
boots Red Hat Enterprise Linux. If your system only uses Red Hat Enterprise Linux,
you should choose the MBR.
