Installation guide

Intel® 64 Systems

You can boot the installation program using any one of the following media (depending upon

what your system can support):

• Red Hat Enterprise Linux DVD/CD-ROM — Your machine supports a bootable DVD/

CD-ROM drive and you have the Red Hat Enterprise Linux CD-ROM set or DVD.

• Boot CD-ROM — Your machine supports a bootable CD-ROM drive and you want to per-

form network or hard drive installation.

• USB pen drive — Your machine supports booting from a USB device.

• PXE boot via network — Your machine supports booting from the network. This is an ad-

vanced installation path. Refer to Chapter 31, PXE Network Installations for additional in-

formation on this method.

To create a boot CD-ROM or to prepare your USB pen drive for installation, refer to Section 4.2,

“Making an Installation Boot CD-ROM”.

Insert the boot media and reboot the system. Your BIOS settings may need to be changed to al-

low you to boot from the CD-ROM or USB device.

Tip

To change your BIOS settings on an x86, AMD64, or Intel® 64 system, watch the

instructions provided on your display when your computer first boots. A line of text

appears, telling you which key to press to enter the BIOS settings.

Once you have entered your BIOS setup program, find the section where you can

alter your boot sequence. The default is often C, A or A, C (depending on whether

you boot from your hard drive [C] or a diskette drive [A]). Change this sequence so

that the CD-ROM is first in your boot order and that C or A (whichever is your typ-

ical boot default) is second. This instructs the computer to first look at the CD-ROM

drive for bootable media; if it does not find bootable media on the CD-ROM drive, it

then checks your hard drive or diskette drive.

Save your changes before exiting the BIOS. For more information, refer to the doc-

umentation that came with your system.

After a short delay, a screen containing the boot: prompt should appear. The screen contains

information on a variety of boot options. Each boot option also has one or more help screens

associated with it. To access a help screen, press the appropriate function key as listed in the

line at the bottom of the screen.

As you boot the installation program, be aware of two issues:

• Once the boot: prompt appears, the installation program automatically begins if you take no

action within the first minute. To disable this feature, press one of the help screen function
