  • Downgrading the BIOS to an earlier version isn't recommended. An earlier BIOS version may not include support for bug fixes, critical security updates, or support the product revisions currently being manufactured.
  • All images in the examples used in the instructions are for illustration purposes only. Make sure to select the correct BIOS files for your Intel® NUC.
  • If a BIOS update process is interrupted, your computer might not function properly. Intel suggests the process be done in an environment with a steady power supply (preferably with UPS).

After any BIOS update, Intel recommends the following steps:

  1. Press F2 during start to enter BIOS Setup.
  2. Press F9 to set BIOS default values.
  3. Customize any BIOS settings, if desired (optional).
  4. Press F10 to save and exit BIOS Setup.

BIOS Recovery by Power Button Menu

In the unlikely event that a BIOS update is interrupted, it's possible the BIOS may be left in an unusable state.

WARNING: This process is intended to be performed by a trained technician.

  1. Download the Recovery BIOS (.bio) file. Example:

    Download the Recovery BIOS file

  2. Copy the recovery file (*.bio) to a USB device.
  3. Plug the device into a USB port of the target computer when it's turned OFF.
  4. Press and hold the power button down for 3 seconds, then release it. The Power Button menu appears.

    Power Button Menu appears

  5. Press F4 to start the BIOS recovery.
  6. Wait 2-5 minutes for the recovery process to complete.

    Wait for the update to complete

  7. The computer will either turn off when the recovery process is complete, or it will prompt you to turn it off.
BIOS Recovery by Security Jumper

BIOS recovery using the BIOS security jumper will clear Trusted Platform Module (TPM) keys, Intel® Platform Trust Technology (Intel® PTT) keys, and High-bandwidth Digital Content Protection (HDCP) keys. These keys won't be restored after the BIOS recovery.

  1. Download the Recovery BIOS (.bio) file. Example:

    Download the Recovery BIOS file

  2. Copy the recovery file (*.bio) to a USB device.
  3. Shut down the computer and unplug the AC power adapter.
  4. Open the chassis and remove the BIOS security jumper. (See the Technical Product Specification for details including the location of this jumper.)

    Remove the BIOS security jumper

  5. Plug the USB device into a USB port of the target computer and turn it on.
  6. Wait 2-5 minutes for the recovery process to complete.
  7. The computer will either turn off when the recovery process is complete, or it will prompt you to turn it off.
  8. Remove the USB device.
  9. Replace the BIOS security jumper.
  10. Close the chassis.
  11. Restart the computer.

When using the Recovery by Security Jumper method, if the Intel NUC starts with the message "Detected BIOS Security Jumper Removed" and lists several menu options, it means the .bio file on the USB flash drive wasn't detected.

Try the following:

  • Check that the file was successfully copied to the USB flash drive.
  • Download and use a new copy of the .bio file.
  • Try a different USB flash device.
  • Try reformatting the USB flash drive without using the Quick Format option. Be sure to backup and save your data from the USB flash drive first.
Express BIOS Remote/Silent Update

Runs the Express BIOS update from a batch file without the need for user intervention. This is useful for remote BIOS updates when user interaction is not desired.

  1. Download the Express BIOS update file (.EB.msi) for your Intel NUC. Example:

    Express BIOS update file

  2. Download and install any utility (such as 7-Zip) that allows you to extract files from an .msi file.

    Download and install any utility

  3. Extract files to a folder.
  4. Open a text editor such as Notepad to create a batch file that contains only the following two lines:

    DPInst.exe /q /f /se
    Shutdown /r /t 10 /c "Upgrading the BIOS. The computer will reboot in 10 seconds" /f /d p:0:0

    Command line switch notes

    DPInst.exe
    /q Sets the quietInstall flag to ON, which suppresses the display of wizard pages, user dialog boxes, and other user messages that DPInst and Windows generate.
    /f Sets the forceIfDriverIsNotBetter flag to ON, which configures DPInst to install a driver on a device even if the driver that is currently installed on the device is a better match than the new driver.
    /se Sets the suppressEulaPage flag to ON, which configures DPInst to suppress the display of a EULA page.
    Shutdown
    /r Restarts the computer after shutdown.
    /t xx Sets the time-out period or delay to XXX seconds before a restart or shutdown. This causes a warning to display on the local console. You can specify 0-600 seconds. If you don't use /t, the time-out period is 30 seconds by default.
    /c "comments"

    Enables you to comment in detail about the reason for the shutdown. You must first provide a reason by using the /d option. You must enclose comments in quotation marks. You can use a maximum of 511 characters.

    You're about to be signed out

    /f Forces running applications to close without warning users. Caution: Using the /f option might result in loss of unsaved data.
    /d p:0:0 Lists the reason for the system restart or shutdown. The value p indicates that the restart or shutdown is planned.
  5. Save the batch file:
    • Save it to the same folder as the extracted files.
    • The file extension must be .bat.
    • Save the file as type All Files (*.*).

      Save the file

    • Copy the folder with all files to the target Intel NUC.
    • Open a Command Prompt in Administrator mode (PowerShell isn't supported):
      1. Click the Windows button and type Command Prompt.
      2. Right-click on Command Prompt and select Run as Administrator.
    • In the Command window, navigate to the folder containing the BIOS update files and the .bat file.
    • Type the complete .bat file name and press Enter to launch the update process.
    • Windows restarts and the BIOS update process begins.
    • After the update is complete, the system starts Windows.

If you’re using BitLocker to enable encryption on a system drive:

•    You might run into issues when performing a BIOS update, such as having to enter a recovery key during startup. 
•    You can modify the .BAT file (sample below) to temporarily suspend BitLocker (and then resume after one reboot).

manage-bde -protectors -disable C: -RebootCount 1
DPInst.exe /q /f /se
Shutdown /r /t 10 /c "Upgrading the BIOS. The computer will reboot in 10 seconds" /f /d p:0:0

•    For more information, see How to Suspend BitLocker Using Command Prompt.
