You can customize the Boot menu options. For information about downloading and extracting Boot images, see Extracting Red Hat Enterprise Linux boot images.
The Boot menu customization involves the following high-level tasks:
- Complete the prerequisites.
- Customize the Boot menu.
- Create a custom Boot image.
3.1. Customizing the boot menu
The Boot menu is the menu which appears after you boot your system using an installation image. Normally, this menu allows you to choose between options such as Install Red Hat Enterprise Linux, Boot from local drive or Rescue an installed system.
To customize the Boot menu, you can:
- Customize the default options.
- Add more options.
- Change the visual style (color and background).
An installation media consists of a GRUB2 boot loader. The GRUB2 boot loader is used on systems with UEFI firmware.
Customizing the boot menu options can especially be useful with Kickstart. Kickstart files must be provided to the installer before the installation begins. Normally, this is done by manually editing one of the existing boot options to add the inst.ks= boot option. You can add this option to one of the pre-configured entries, if you edit boot loader configuration files on the media.
