I am not from Intel and I think you've provided lots of info which might help someone else investigate. But just in case, there was a slightly similar previous thread which would lead me to two questions. First, is there an OS installed on that SSD? I'm not clear that the difference is just SSD attached, but rather it may be that SSD is starting to boot (then maybe involving something else like display driver). Second, are you able to try a different monitor setup? For example if you are plugged HDMI perhaps through something like Audio Visual Receiver and then to some input of a TV, are you able to try plugging NUC direct to some more traditional computer monitor or perhaps more directly to some input on your TV (such as #1) which has spec saying that it supports PCs? The reason I ask is that some code in NUC BIOS and/or drivers seems to often have compatibility issues with certain devices (it seems to be trying to read capabilities such as resolution so that it can do things like display Visual BIOS 1024x768 centered within your resolution).
Thanks for trying; I do have Windows installed, and can boot to it -- I just can't boot to it again.
I should also mention that I have the most recent BIOS and that nothing is recorded to the BIOS event log when it fails to boot. I have disabled everything in the BIOS settings that I don't use, tried with and without fast boot, and reset to default settings, but nothing helps. I removed the CMOS for 20 minutes as well.
Again, sorry if it did not help. I thought the other thread was saying stuff like could not reboot after using the header power pin and I think was saying that results varied if he changed Control Panel-Hardware and Sound-Power Options-System Settings "Turn on fast startup" option from the default (enabled) to the non-enabled setting (not to be confused with Intel's fast boot settings in the BIOS). And his HDMI was connected through AVR which seems to cause frequently reported problems here with things like resume from hibernate (which is sort of the way Windows fast startup works).
