An error during partition resizing can lead to irreversible data loss. It is recommended to create a backup beforehand and to take a snapshot on the hypervisor side after expanding the virtual hard drive.

It is possible to enlarge the system partition afterwards; to do so, proceed as follows:

  1. Set up an admin account for the terminal
    To do this, navigate to kommbox →  System/Users → Root-Terminal-Password , and activate the admin account."
