iFlash BIOS Update Instructions

The iFlash BIOS update utility allows you to update the BIOS from a bootable USB device. Information on how to create a bootable USB device is at the end of this document. See instructions, or print and use the .PDF version.

  • Update the BIOS on your computer only if the newer BIOS version specifically solves a problem you have. We do not recommend BIOS updates for computers that do not need it. You can view all BIOS changes in the Release Notes included on the BIOS download page in Download Center.
  • Downgrading the BIOS to an earlier version is not recommended and might not be supported. An earlier version might not support the latest processors, bug fixes, critical security updates, or board revisions currently being manufactured.
  • Before initiating a BIOS update, be sure to read and precisely follow the instructions included in this document. You can print the instructions for easy reference.
  • Do not 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 that have been changed (from default) so they can be restored 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.

All BIOS update files for Intel® NUC products are available on Download Center.
