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
