Boot in Emergency Mode

If you encounter problems during normal boot, you can boot in Emergency Mode.

Perform the following steps to boot in Emergency Mode:

  1. Restart the Photon OS machine or the virtual machine running Photon OS.

    When the Photon OS splash screen appears, as it restarts, type the letter e quickly.

  2. Append emergency to the kernel command line.

  3. Press F10 to proceed with the boot.

  4. At the command prompt, provide the root password to log in to Emergency Mode.

    By default, / is mounted as read-only.

    To make modifications, run the following command to remount with write access:

    mount -o remount,rw /
