I am not from Intel and I am not sure what you are asking, but maybe it is this. The system sometimes is set to boot fast without displaying BIOS stuff. In cases like that if you want to get to BIOS settings on recent NUCs there is a way called something like Power Button Menu (replaced old method involving jumper). It is described in the manual, from a power off you hold the power button down for a specific number of seconds like 3-4, then when you release it should show a special text menu where one of the options is BIOS settings.
So after leaving without power for a day it seems to have "Returned to normal".
Just to be sure I booted it up a bunch of times to check but it diden't manifest again.
Also I can add that without a doubt fast boot was off it had nothing to with that or my boot times even on legacy boot would have been several times faster (ie: boot time was basicly 3 seconds with fast boot 1.5 seconds maybe 1.3 second boot)
Guess Ill update the bios and see what happens.
Still on the same bios version (have not re-flashed) and the behavior stays the same.
However I have a few things to add.
-The monitor does not accuse lack of signal (as sit normally does when there is no image being sent to it)
-The computer still boots into the OS just fine
-Using the Fast boot fix that was said by the user before me does nothing but keeping it locked down on a black screen (which I assume it did it's intended purpose of getting in the bios but it's not sending any image to display other then a black background)
So i'm going to unplug it from the power brick and leave it to idle for a few hours and install the new bios version (pray to god it doesn't brick)
Kinda disappointed that basically no one from either the intel staff nor the community wants to help.
Guess i'm rma'ing this as a faulty bios chip and exchanging it for a new one.
Still gonna hold on to it for a another couple of days if anyone knows anything i'm still lurking on this thread.
Also I have been unable to get the bios splash screen so i'm still running the same version of the bios.
Alright did the bios recovery method, still no boot splash screen.

But behavior has not changed, I still get no splash screen and after a few moments it boots straight off to the OS, ill try to get another screen to test if it's really not a bios problem.
But ill add the screen model i'm using yet again.
Samsung Synchmaster SA350
Well this nuc thing is making me run around in circles and is In fact proving to be one of my worst choices as a consumer hardware (could have aquired some cheezy gamer laptop for the same price with a dedicated gpu and i'd still have less problems, sorry about the rant i'm just infuriated).
So here's what exactly happened.
Plugged the NUC in 12 different panels (using 5 different cables to be 100% sure this isn't a random behavior) .
2 Samsung HD TV's.
6 Sony Bravias.
2 Asus Monitors.
I'm pretty sure by know you know what happened, yeh old black boot no splash screen.
So I go back into my office to put the NUC back into its corner plug it back in to the outlet and to the screen and I power it on... It shows the Grub boot loader which it hadn't in a while, so as a reflex I quickly tap ctrl+alt+delete and smack the f2 like there was no tomorrow and wouldn't you know it the bios menu showed up.
Here's the rotten side of the deal, why is this happening,
Why does it boot directly into the OS and it doesn't display the bios,
What kind of problem is prompting this,
And how can I get to the bottom of it.
All these generic answers by the intel staff is most annoying i'm no specialist in bloody bios programming but I can troubleshoot hardware just fine, and this usually indicates either a bad/defective motherboard or bad bios chip.
But since i'm no expert at diagnostics the underlying cause and no one has yet to ask me to get any logs i'm getting quite anoyed so help me out over here.
