Chapter 29. Installing Without Media


This procedure assumes you are already using Red Hat Enterprise Linux or another relatively modern Linux distribution, and the GRUB boot loader. It also assumes you are a somewhat experienced Linux user.
This section discusses how to install Red Hat Enterprise Linux on your system without making any additional physical media. Instead, you can use your existing GRUB boot loader to start the installation program.

29.1. Retrieving Boot Files

To perform an installation without media or a PXE server, your system must have two files stored locally, a kernel and an initial RAM disk.
Copy the vmlinuz and initrd.img files from a Red Hat Enterprise Linux DVD (or DVD image) to the /boot/ directory, renaming them to vmlinuz-install and initrd.img-install. You must have root privileges to write files into the /boot/ directory.
