My apologies for the inconvenience.
To resolve this error, change the boot drive order in BIOS Setup:
- Press F2 during boot to enter BIOS Setup.
- Go to the Boot menu.
- Set LAN or Network Boot to be the last boot option.
- Press F10 to save and exit the BIOS Setup.
We use this suggestion for Intel® Motherboard, but it could so please give a try on your Intel® NUC. See the documentation here: PXE-E61 Media Test Failure Error
Please let me know how it goes.
