Installation guide

DVD?

There are several methods that can be used to install Red Hat Enterprise Linux.

Installing from a CD-ROM or DVD requires that you have purchased a Red Hat Enterprise Linux

product, you have a Red Hat Enterprise Linux 5.0.0 CD-ROM or DVD, and you have a DVD/

CD-ROM drive on a system that supports booting from it.

Your BIOS may need to be changed to allow booting from your DVD/CD-ROM drive. For more

information about changing your BIOS, refer to Section 3.1, “Booting the Installation Program on

x86, AMD64, and Intel 64 Systems”.

4.1. Alternative Boot Methods

Boot DVD/CD-ROM

If you can boot using the DVD/CD-ROM drive, you can create your own CD-ROM to boot

the installation program. This may be useful, for example, if you are performing an installa-

tion over a network or from a hard drive. Refer to Section 4.2, “Making an Installation Boot

CD-ROM” for further instructions.

USB pen drive

If you cannot boot from the DVD/CD-ROM drive, but you can boot using a USB device,

such as a USB pen drive, the following alternative boot method is available:

To boot using a USB pen drive, use the dd command to copy the diskboot.img image file

from the /images/ directory on the DVD or CD-ROM #1. For example:

dd if=diskboot.img of=/dev/sda

Your BIOS must support booting from a USB device in order for this boot method to work.

4.2. Making an Installation Boot CD-ROM

isolinux (not available for Itanium systems) is used for booting the Red Hat Enterprise Linux in-

stallation CD. To create your own CD-ROM to boot the installation program, use the following

instructions:

Copy the isolinux/ directory from the Red Hat Enterprise Linux DVD or CD #1 into a temporary

directory (referred to here as <path-to-workspace>) using the following command:

cp -r <path-to-cd>/isolinux/<path-to-workspace>

Change directories to the <path-to-workspace> directory you have created:

cd <path-to-workspace>

Make sure the files you have copied have appropriate permissions:

chmod u+w isolinux/*

Finally, issue the following command to create the ISO image file:
