EFI Shell

Causes of errors

The error occurs if the UEFI option is activated in the BIOS. In this case, in some cases the EFI shell is called up during PC startup.

Troubleshooting

Start the BIOS while the PC is booting.

  1. Switch on the computer of the milling machine.
  2. For most milling machines, you must press the "Unf" key. This is located on the keyboard to the right of the Enter/Down key.
  3. This takes you to the BIOS of the milling computer.
  4. Select "Boat options„
  5. There should be an option "UEFI". Change this value to "Normal„.
  6. Save the changes and restart the computer.

The error should no longer occur. If the error still occurs, please contact GeBioM mbH Support.
