NUC BIOS Update Gone Wrong

Bought a NUC5i5RYK and booted it up for the first time. Decided that a BIOS update was in order and grabbed RY0385.bio and loaded it onto a USB drive.

Next thing I know my screen is blank and I have no boot screen on boot. Nothing visible at all.

I pulled the security jumper after the other BIOS recovery operations failed and powered on the NUC, but no joy.

Do I have any other options here?

Thanks!

Power on pressing the power button for ~3 seconds. This should result in the Power Button Menu (PBM) being presented on-screen after a short time (30 seconds max). If you can get to the PBM, you can use F2 to get into BIOS Setup (where you should reset the BIOS configuration). You can also use F4 to start a BIOS Recovery process (use the latest BIO file for this).

Hope this helps,

Thank you, I've tried that and it didn't work

Well, a hard clear of CMOS might be in order. Unplug power and all attached cables. Open bottom and remove the two screws holding the board down. Pry up on the front edge of the board and lift board until you can reach to battery cable on opposite side. Unplug battery for 15 minutes. There is video that can help do this: https://www.youtube.com/watch?v=3m0dJhF3CEg.

Thanks Scott. Pulled the power from the cmos and that didn't work either. I've also pulled the SSD. Not sure what could explain this.

Ok. Last thing we can try is the jumper-based BIOS Recovery process. Here are the instructions:

  1. NOTE: Read these instructions completely before starting. Follow all instructions EXACTLY.
  2. On some other Windows-based PC, make sure that you have the .BIO file for the BIOS release you wish to reinstall.
  3. Insert a 32GB or smaller (the smaller the better) USB 2.0 flash drive into the PC. It is best if you use a flash drive that has an access LED that you can watch.
  4. Format this USB flash drive using the Windows Format applet. Select to install the FAT32 file system (NOT vFAT, NOT exFAT; FAT32 only). You must also specify that the Quick Format option be Disabled (unchecked).
  5. NOTE: If FAT32 is not offered as a choice by the Format applet, your flash drive is too big; use another.
  6. Copy the .BIO file into the root folder of this USB flash drive. This should be the only .BIO file in the root folder of the USB flash drive.
  7. Properly eject the USB flash drive. Do not just yank it out. Do this from File Explorer or using the Safely Remove Hardware and Eject Media System Tray applet.
  8. Power off the NUC, flip it over and remove its bottom cover.
  9. Remove the yellow BIOS Configuration jumper from the board. It will be the only yellow jumper.
  10. NOTE: Remember the pins that this jumper was plugged onto; you will need this information later.
  11. Plug the USB flash drive into one of the USB ports on the back panel of the NUC.
  12. Power on the NUC.
  13. The BIOS Recovery process should start automatically. You should see a progress report on your main monitor.
  14. NOTE: If you do not see a progress report displayed on your monitor, do not power off the system for at least 10 minutes. While it is rare, it is possible for the process to proceed without an onscreen display; you must give it ample time to complete, just in case.
  15. When the BIOS Recovery process is complete, you will be asked to power off and unplug the system. Do so.
  16. Restore the yellow BIOS Configuration jumper to the pins it was on previously. This should be across pins 1 and 2 of this (three pin) header.
  17. Remove the USB flash drive from the back panel USB port.
  18. Power on the NUC.
  19. Immediately begin pressing the F2 key, over and over (approx. once per second) until you see the BIOS Setup (or Visual BIOS) screen displayed.
  20. Verify, using the BIOS version string, that the BIOS installed properly. Stop if it isn't.
  21. Press the F9 key (followed by Y) to reset of the BIOS configuration.
  22. Press the F10 key (followed by Y) to save the BIOS Configuration and exit BIOS Setup.
  23. Once screen is cleared (goes black), begin pressing the F2 key, over and over, until you see the BIOS Setup screen displayed.
  24. Make any changes to the BIOS configuration that you desire (for example, disabling NUMLOCK) or that you require (for example, setting Boot Order, enabling UEFI, etc.).
  25. Press the F10 key (followed by the Y key) to save the BIOS Configuration and exit BIOS Setup.
  26. Test.

Hope this works,
