@ttrammell said in Asus ZenBook Flip UX360U - PXE Assistance Needed: UEFI BIOS on the Zenbook still doesn’t recognize the USB-to-Ethernet adapter, FWIW: To get this to work, you need network adapters supported by your hardwares UEFI firmware. Think of uefi as a very limited operating system. If it doesn’t have the drivers built in, then it can’t initialize the device. So if you want to pxe boot on that zenbook you need to contact the manufacturer to find out what usb network adapters are supported by the firmware … or … just boot fos from the usb stick and move on to the next problem.
