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

Note

The following Intel NUC models use the Aptio 5 BIOS core, which uses a different method for BIOS updates and Recovery.

  • Intel® NUC 8 Mainstream-G (NUC8i5INH)
  • Intel® NUC 8 Mainstream-G (NUC8i7INH)
  • Intel® NUC Kit NUC8CCHKR
  • Intel® NUC Board NUC8CCHB

See BIOS Update and Recovery Instructions for Intel® NUCs With Aptio 5 BIOS. 

 

Note

  • All BIOS update files for Intel® NUC products are available on Download Center.
  • This process is intended to be performed by a trained technician.
  • Downgrading the BIOS to an earlier version isn't recommended and might not be supported. An earlier BIOS version may not support the latest processors, bug fixes, critical security updates, or the board revisions currently manufactured.
  • Don't interrupt the BIOS update process. We recommend the process be done in an environment with a steady power supply (preferably with UPS).
  • Before updating the BIOS, manually record all BIOS settings you changed (from default) so they can be restored after completing the BIOS update.

See the two options below to perform a BIOS recovery.

Click or the topic for details:

BIOS Recovery by the Power Button Menu
  1. Download the Recovery BIOS (.BIO) file. Example:

  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 or 4 seconds, until the power button LED turns orange, then release the button.

  5. The Power Button menu appears:

  8. The computer turns off when the recovery process is complete, or it prompts you to turn it off.

BIOS Recovery by the Security Jumper

Note

The BIOS security jumper recovery clears all AMT settings, Trusted Platform Module (TPM) keys and Intel® Platform Trust Technology (Intel® PTT) keys.
  1. Download the Recovery BIOS (.BIO) file. Example:
    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.

  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 turns off when the recovery process is complete, or it prompts you to turn it off.
  8. Remove the USB device.
  9. Replace the BIOS security jumper.
  10. Close the chassis.
  11. Restart the computer.

Note

When using the Recovery by Security Jumper method, if the Intel NUC boots to 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.
