Chapter 3. Installing Red Hat Enterprise Linux ES 31
The first sector of your root partition
Recommended if you are already using another boot loader on your system (such as OS/2’s Boot
Manager). In this case, your other boot loader will take control first. You can then configure that
boot loader to start GRUB (or LILO), which will then boot Red Hat Enterprise Linux ES.
Caution
If you have a RAID card, be aware that some BIOSes do not support booting from the RAID card. In
cases such as these, the boot loader should not be installed on the MBR of the RAID array. Rather,
the boot loader should be installed on the MBR of the same drive as the
/boot
partition was created.
Select where you would like GRUB (or LILO) to be installed on your system. If your system will use
only Red Hat Enterprise Linux ES, you should choose the MBR.
If you want to add default options to GRUB or LILO’s boot command, enter them into the
Kernel
parameters field. Any options you enter will be passed to the Linux kernel every time it boots.
The
Force use of LBA32 (not normally required)
option allows you to exceed the 1024 cylinder
limit for the
/boot
partition. If you have a system which supports the LBA32 extension for booting
operating systems above the 1024 cylinder limit, you shouldplace your
/boot
partition above this
limit. If the installation program has not already detected this extension from your BIOS, you should
select the
Force use of LBA32 (not normally required)
option.
Every bootable partition is listed, including partitions used by other operating systems. The partition
holding your Red Hat Enterprise Linux ES system’s root filesystem will have a
Boot label
of
Red
Hat Enterprise Linux ES
. Other partitions may also have boot labels. If you would like to add
boot labels for other partitions (or change an existing boot label), click once on the partition to select
it. Once selected, you can change the boot label by editing the name in the Boot label text field.
Note
The Boot label column lists what you must enter at the boot prompt in order to boot the desired
operating system. However, if you forget the boot labels defined on your system, you can always
press [Tab] at the prompt to display a list of defined boot labels.
3.14.1. Rescue Mode
If you need to use rescue mode, there are several options available to you.
•
Using the CD-ROM to boot, type
linux rescue
at the
boot:
prompt.
•
Using the network boot disk you have created, type linux rescue at the
boot:
prompt. You
will then be prompted to retrieve the rescue image from the network.
•
Using the boot disk you have created, type
linux rescue
at the
boot:
prompt. You then pick
an installation method and choose a valid installation tree to load from.
For more information regarding rescue mode, refer to the Official Red Hat Linux Customization Guide .
