The N.Scott.Pearson answer is the answer I agree with. Since after you have set to Fast Boot, the F2, F7, F10 menu is not longer displayed, you can enter to your bios from within Windows 10 and cancel the Fast Boot setting. You can follow the following instructions: Windows 10 Forums .
Sorry for my poor English and I had said windows 10 “Shift + reboot” to F8+reboot, also for there are spell mistakes for there is no spell checking in Intel forum.
I normally turn off my NUC by a custom timer procedure. I set bois to “fast boot” so that I can save a few seconds next time when I turn on NUC.
With fast boot, I can’t into bios by press F2, so the only way is press “Shift” key then use windows 10 reboot. This boot will boot into BIOS setting page, but it will hang up. No keyboard or mouse will respond. I think it should be a bug, but I don’t know if it were from Intel or from Microsoft.
In this hanged up page, the only thing I can do, is turn off the NUC by press “power button”, and the press it again to turn on the NUC. Fortunately this time I can use F2 to going into the BIOS setting page.
The win10 do know that I was not boot into the BIOS setting properly, so after I setup the BIOS, win10 prompt me if I will use fast boot again. Normally I will reply “Y” to continues use fast boot, because no bios set should do everyday.
Thanks and regards
Dear William Wang
No I believe that I understand your problem:
1. You have set I bios Fast Boot to shorten NUC boot time and because of the Fast Boot setting you are entering Bios setting trough Windows 10 Advanced Menu (after pressing shift+restart from Windows.
2. While you are in Bios, the keyboard and mouse are not responding and you are forced to press Power button to shut down the NUC.
Now I'll give you my comments to the above problem
1. First off all I just realized that you are using DDR4 2400MHz RAM and this memory is not compatible with your NUC. In this forum many problem of system hanging have been reported by other users, using 2400MHz memory. You shall use DDR4 2133MHz RAM. See the table with compatible memory: System Memory for Intel® NUC Kits NUC7i[x]BN
2. Do not use Fast Boot setting. I've checked it and practically this setting is not shortening boot time, it cause only inconveniency.
3. Is a Advanced, Devices, USB Legacy setting in your Bios checked? It should be checked in order to have you keyboard functional in Bios. Any way I suggest that first you shall reset your bios to default setting (press F9 and then F10 followed by "Y" to save and exit ). See how it works in default settings.
4. Since your keyboard is not responding while you are in Bios settings, before setting Bios as I have written in para. 3 above, perform Bios Recovery: BIOS Recovery Update Instructions for Intel® NUC .
- Try to reach the Power button menu to perform a Bios recovery:
Push the power button and hold it down for 3 seconds. In order to get Power Boot menu, you shall release the power button before the 4-second shutdown override. The system will emit three short beeps from the front panel (FP) audio port (if you have connected speaker), then you shall release the power button. The FP power n LED will also change from Blue to Amber when you can release the power button. Press F4 (the USB with BN0046.bio inserted in USB port) and the recovery shall start. By the way from the Power Button menu pressing F3 will disable Fast Boot.
- If you like, you can use the Security jumper removed method with is executed automatically without need to press F4 from menu. The latest BN0046.bio file you can find here: Download BIOS Update [BNKBL357.86A]
Hope this will help
