Enable systemd-boot Menu

The default installation of Clear Linux OS does not set a timeout value for the systemd-boot bootloader. At boot time, you will not be presented with the systemd-boot menu. Without a menu, you cannot interact with systemd-boot such as selecting a different kernel, editing kernel command line parameters, etc.

To set a timeout value for the systemd-boot menu, follow these steps:

  1. Boot up Clear Linux OS.

  2. Log in.

  3. Set a timeout (for example: 20 seconds).

    sudo clr-boot-manager set-timeout 20
    
  4. Reboot.
