28.6. Using the Maintenance Boot Modes

28.6.1. Verifying boot media

You can test the integrity of an ISO-based installation source before using it to install Red Hat Enterprise Linux. These sources include DVD, and ISO images stored on a hard drive or NFS server. Verifying that the ISO images are intact before you attempt an installation helps to avoid problems that are often encountered during installation.
Red Hat Enterprise Linux offers you two ways to test installation ISOs:
  • select OK at the prompt to test the media before installation when booting from the Red Hat Enterprise Linux DVD
  • boot Red Hat Enterprise Linux with the option mediacheck option.
