We bought a NUC (Intel NUC Kit DN2820FYKH (BOXDN2820FYKH0)) and Memory (Kingston ValueRAM SO-DIMM 2GB DDR3L-1600, CL11 (KVR16LS11S6/2)). However, we cannot boot the NUC from a USB pendrive. It always states "The bootable device has not been detected". Moreover, the EFI doesn't detect any Memory, saying there are 0 GB (although the SO-DIMM is definitely installed correctly). Also, the USB drive actually is bootable which we tested with a laptop computer.
What could be wrong with the device/setup?
