I'm using USB DVD drive with Windows 8 ISO from MSDN. This combination of disk and drive is working perfectly with other UEFI-capable motherboards, but NUC just doesn't see it as UEFI device.
I've loaded defaults and tried many different settings, but to no avail.
I'm using the latest 0039 bios, and also tried flashing 0032, but it didn't work either. NUC is the model DC3217BY with thunderbolt.
Others here said that they had some working solution. But so far no one really provided a guide that worked for them. If you've got it working either from USB DVD or USB Flash drive, could you please post the guide that you were following.
