1. My advice how to install manually Ethernet driver see here: Re: Ethernet Driver NUC7i5BNH
2. You can boot into your UEFI Bios setting from Windows. Use the following guide: Windows 10 Forums . After you enter your Bios, press F0 to set bios defaults settings, followed by "Y" (yes). Then press F10 to save the settings and exit Bios.
Hope this helps
Thank you very much Leon !
I have not tried the uefi bios manoeuvre, but the ethernet is now installed
Have a nice day !
