2.4. Can You Install Using the CD-ROM or 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 5.3 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 4.3.1, “Booting the Installation Program on x86, AMD64, and Intel® 64 Systems”.

2.4.1. 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 installation over a network or from a hard drive. Refer to Section 2.4.2, “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.
