Windows® 10 usually creates the 4 partitions necessary to install the operating system. I suggest you to do the following. Get into the BIOS, press F9 then, F10 (Reset BIOS settings); restart the NUC and get into the BIOS again, verify if M.2 option is checked at Advanced>Devices>PCI
Plug the USB Windows® 10 bootable drive to the NUC and start the NUC. Keep tapping F10 and select UEFI – USB Windows® bootable drive then, format the Solid State Drive or erase the current partitions and install the operating system again.
