Can I update the NUC's Visual BIOS from UEFI?

Resolution

The UEFI Flash BIOS update utility allows you to update the Visual BIOS from the EFI Shell.

NoteMost Intel NUCs that shipped in 2019 and later use the Aptio V* BIOS core and not the Visual BIOS.  For those models, see BIOS Update and Recovery Instructions for Intel® NUCs with Aptio 5 BIOS

Please select boot devices

  1. Download the UEFI Flash BIOS Update file (*.UEFI.zip). Example:

    Available downloads

  2. Double-click the *.UEFI.zip to extract its files.

  3. Copy UefiFlash.efi and the .bio file to the bootable USB device.

  6. Press F10 during start to open the Boot Menu.
  7. Select UEFI: Built-in EFI Shell.

    Example: if your USB drive is fs3, then type fs3: and press Enter.
  9. At the command prompt, type UefiFlash.efi XXX.bio, where XXX.bio is the filename of the .bio file and press Enter.
