How to create CD, DVD, or USB media to install Red Hat Enterprise Linux

This article describes how to create a Red Hat Enterprise Linux installation CD, DVD, or USB.

Prerequisite

Download the ISO installation image from the Customer portal Downloads page.

Using the ISO to Create a Bootable DVD

To create (burn) a CD or DVD, write the ISO to the disc on command line using the cdrecord utility.

Example:

[root@host ~]# cdrecord -v -dev='/dev/xxxx' yyyy.iso

Where /dev/xxxx is the USB device, and yyyy.iso is a Red Hat Enterprise Linux installation image. Use the command cdrecord --devices to list disc-writing devices and identify the correct device to use.

NOTE: A standard single-layer, single-sided DVD can hold up to 4.7GB. If the iso image is larger than that, then a single-layer, dual-sided (9.5GB), dual-layered, single-sided (7.5GB) or BluRay DVD (25GB) will need to be used to hold the iso image.

Using the ISO to create a Bootable USB Drive

Alternatively, to create bootable USB installation media, write the ISO image to the USB device using the dd utility.

Example:

[root@host ~]# dd if=yyyy.iso of=/dev/xxxx status=progress

Where /dev/xxxx is the USB device, and yyyy.iso is a Red Hat Enterprise Linux installation image. Use the command fdisk -l to list disk devices and identify the correct USB device to use.
