Power Button Menu BIOS Update Instructions for Intel® NUC


Install & Setup



The Power Button Menu Update allows you to update the system BIOS during the boot process and before the operating system loads.


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. 



  • All BIOS update files for Intel® NUC products are available on Download Center.
  • Downgrading the BIOS to an earlier version is not recommended, and may not be supported. Earlier versions might not support the latest processors, bug fixes, critical security updates, or board revisions currently manufactured.
  • Don't interrupt the BIOS update process. For best results, use an uninterruptible power supply (UPS) to complete the BIOS updates.
  • Before updating the BIOS, manually record all BIOS settings that you changed (from default) so you can restore them after completing the BIOS update.
  • All images in this example are for illustration purposes only. You need to select the correct BIOS files for your Intel® NUC.


  1. Download and save the Recovery BIOS (.BIO) file to a portable USB device. Example:
