Hi,
I have a new NUC 8i5BEH with 8 gb ram and 240 gb M.2 SSD drive.
I have updated the latest BIOS: 0073.bio and have created a factory reset disk image (.img.gz) onto a 1 gb usb flash drive using Etcher. However despite multiple attempts, when I boot the NUC and press F10 it only recognises the ethernet ports as bootable source and not the usb flash drive. Does anybody know what am I doing wrong? Help!
