Making Media

This chapter describes how to use ISO image files obtained by following the steps in Downloading CentOS to create bootable physical media, such as a DVD or a USB flash drive. You can then use these media to boot the installation program and start the installation. These steps only apply if you plan to install CentOS on a 64-bit AMD, Intel, or ARM system, or an IBM Power Systems server using physical boot media. For instructions on how to set up a Preboot Execution Environment (PXE) server to perform a PXE-based installation over a network, see Preparing for a Network Installation.

By default, the inst.stage2= boot option is used on the installation media and set to a specific label (for example, inst.stage2=hd:LABEL=CentOS\x20Server.x86_64). If you modify the default label of the file system containing the runtime image, or if using a customized procedure to boot the installation system, you must ensure this option is set to the correct value. See Specifying the Installation Source for details.
