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 CD-ROM or DVD, and you have a DVD/CD-ROM drive on a system that supports booting from it.
2.4.2. Making an Installation Boot CD-ROM
isolinux (not available for Itanium systems) is used for booting the Red Hat Enterprise Linux installation 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:
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:
mkisofs -o file.iso -b isolinux.bin -c boot.cat -no-emul-boot \ -boot-load-size 4 -boot-info-table -R -J -v -T isolinux/
The above command was split into two lines for printing purposes only. When you execute this command, be sure to type it as a single command, all on the same line.
Burn the resulting ISO image (named file.iso and located in <path-to-workspace>) to a CD-ROM as you normally would.
