NUC 8BEH not booting after migration to win 11 and installing BIOS download

Hi there, 

my NUC 8i3BEH migrated from Windows 10 to Windows 11 yesterday without any problems. NUC is booting and Win 11 is running. Today I have allowed to do a BIOS update. Windows has downloaded the files and after restarting it is not booting anymore. It shows the following sequence on power led with  green light: 2 s on, 4 sec off, 6 s on, 4 sec off and then repeated. This sequence is not listed in support material. I cannot access BIOS menu via F2. I have removed the RAM which gives a RAM not detected indication on LEDs and removed and reinstalled SSD with no success. Voltage of power supply is 19V. So should be ok. Any help much appreciated. I have no clue what to do next.

Regards, Tomato123

Hi @Tomato123 

Try to recover BIOS, using BIOS Recovery from the Power Button Menu:


1. Prepare USB stick fully formatted to FAT32 (disable quick format option during format). Format your USB on Windows machine (rather than Linux or MAC). Save the Bios file BE0089.bio on this stick and insert it into front USB slot with amber color (NUC shall be OFF). You may use also one of the rear USB ports (do not use front blue USB port, since sometime the USB stick is not recognized during boot process).
2. Press and hold Power Button for about 3 seconds. Count 1001, 1002, 1003,1004. Release the Power Button. NUC should reboot into Power Button Menu. You should release the Power Button before 4-sec shut down override or when the Power Button LED changes color from blue to amber.
3. Press F4 and the recovery shall start (it can take up to 30 seconds for messages to appear on the screen).
When the recovery finishes, press on Power Button and hold it, until NUC switches OFF. Pull out the power cord. Remove the USB stick.
4. Replace the power cord and press Power Button to switch the computer to ON.
While you see the Intel NUC logo, enter Bios setting by pressing F2 during boot process.
5. Press F9(followed by "Y"), to set Bios to default settings. Press F10 (followed by "Y"), to save the settings and exit to O.S. Let the NUC fully reboot.
6. If before update, you have customized bios settings, you can enter again to Bios setting to change the necessary settings.

Hi, 

thanks very much. It worked. All fixed. Unfortunately, there is no official solution to the problem from Intel.

(blink sequence not listed).

Actually, I might suggest doing a CMOS reset before attempting recovery.
