Have you installed all drivers for your NUC? : Downloads for Intel® NUC Kit NUC7i5BNH
If you haven't yet, you shall do it. You can download each driver separately or you can download Driver Bundle zip and unzip on your drive before installation of each driver.
Install each driver manually (do not use Intel Update Driver Utility).
Start first with Management Engine driver and with Chipset Driver. Reboot your computer.
Now, you can install all other drivers - the sequence is not important. You don't need to reboot your NUC after each driver, only once in the end.
Update your bios to the latest version using Bios recovery method (you can choose Power Menu option): BIOS Recovery Update Instructions for Intel® NUC
To get the Power Button menu, press the Power Button for 3 seconds (but not more than 4 seconds). Release the Power Button once the Power Led changes its color from blue to amber. NUC will boot into Power Button menu.
3. While the USB stick with the BN0050.bio file is inserted into USB socket, press F4 to initiate the bios recovery process.
