As this issue only happens on cold boot, have you checked whether there's an updated BIOS for your system? And does it really not boot or are you 'only' getting no display output? If the latter, can you ssh into your NUC and share `dmesg` output? Hopefully that'll give a clue as to why the DP/HDMI outputs aren't working properly.
