Please help, thanks in advance.

The bios doesn’t provide enough resources for the K20. Since it’s really old, please check

  • for a bios update
  • whether the mainboard supports “Above 4G decoding”
  • UEFI boot
    Then enable “Above 4G decoding”, disable CSM and reinstall Ubuntu in UEFI mode.
