Choose the UEFI USB boot option using the cursor keys.

Press Enter once the UEFI option is chosen, then highlight Customer Factory Reset, and press Enter. This option will detect your installation and try to keep network configurations, hostname and /data partition. We recommend backing up data prior to proceeding with this step wherever possible.
