thank you for this suggestion. I will try it asap.
I am just wondering, that i can start the update in different ways without any fail massage. I just get a black screen after starting the update for a few seconds and then the PC starts completly in normal way the OS. It seems like the update aborted.
I try 3 ways:
- The Windows way (the result after rebooting says: Successfully updated...!!?!)
- F2, than click on update
- the F7 way
Maybe it is necessary to deactivate any protection mode in Bios? Or to Change to factory Default?
Is there any requirements to the usb stick? I formated it with Windows to Fat32...
Is it maybe helpful to remove ssd and ram for BIOS updating?
Is there a special USB Port for updating?
Regardless of what method you use - Windows (EBU), F2, F7, DOS (iFlash) or even the Recovery process - what happens is the same. The application (or, for F2 and F7 methods, the BIOS itself) loads the update capsules into memory and then causes the system to do a reboot. During the reboot, the BIOS sees that there are update capsules in memory and will process them (check their integrity, decompress and decrypt them, verify their signatures and then install them). The Recovery Process is a little more involved, but I won't go into that. Since you will probably ask, the reboot step in the middle of the process cannot be avoided; it is part of the security measures implemented in the process; it ensures that the known, running BIOS (whose integrity has already been verified) is in control of the update process.
When the reboot occurs, the BIOS is still going to go through its POST processes before handling the capsules in memory. There are very few things that can cause it to abort and not process the capsules. The main thing that can cause this is problems initializing RAM. If the RAM initialization has to be repeated, there is the possibility of the capsules in memory being corrupted (because of loss of memory refresh) and, in this case, the update will be aborted.
So, what should you do if this happens? Usually, you just try it again. If it repeats, switch to the F7 method (using a freshly-reformatted USB 2.0 flash stick using FAT32 file system). If this also fails, try using the Recovery Method (documented here: Intel NUC BIOS Recovery Update Instructions).
As for what caused the issue in the first place. I will say this: more things can go wrong using the Windows (EBU) method and I avoid using it myself. If it repeats, I start to look at whether my memory is configured and working properly. At a minimum, I would do a thorough overnight MemTest86+ run to verify that the memory is working properly.
Hope this helps,

At this stage, BIOS recovery would be best option on this Intel® NUC.
Not an actual requirement for the USB flash drive.
You do not need to remove anything off the NUC.
Any USB port will work for BIOS recovery.
i tried to start the bios recovery with holding down the power button for 3 seconds. But this way did not work. there was no triple beep and the OS started in normal way. I tried it over ten times with different amount of seconds...
What was wrong?
So, is it the last way to use the Jumper method?....i was so hopefully that i do not have to use this way.
What will happen to the actually OS Installation after a successfully Bios recovery ? I hope nothing...
1. Try the recovery method with the Bios security jumper removed. Check if the Bios security jumper is not installed in "locked" position (pins 2-3). In order to enable Bios update using F7 method or get Power Menu this jumper should be installed in "Normal" position (pins 1-2). Any way try to recover the Bios with this jumper removed ("Configuration" mode).
2. As Scott mentioned, the USB stick with the bios file should be formatted to FAT32.
It works perfectly for me. You are just not holding it down for the right amount of time. Try doing it for, say, 7 seconds. Count while you do so. If you hear the system power back off while you are still holding it down, then you need to start again and hold it down for slightly less time. Eventually, you will get it to go...
I tried the recovery method with the Bios security jumper removed. Without success....
It is the same problem. I chose F4 for BIOS Recovery. The System shut down. Then it starts, but stop after a few seconds and reboot again. This repeats again and again until i put off the usb stick. i tried 3 different usb sticks with Fat32 format. 8 GB and 4 GB Sticks....
The Power Button Menu:
Is it right, that i push and hold the Button, when the System is off?
There are no numbers at the pins...So let mehr try to explain how it look:
The Jumper is on 1 and 2 when i turned the nuc in direction that the jumper is near to me.
Is this the right Position?
Thx a lot
Looks to me that you have to replace your NUC. If with BIOS security jumper and USB stick correctly formatted, the recovery procedure doesn't start from its self, probably it is hardware problem. Any way I'm attaching pictures:
1. Pin 1 on jumper connector
2. Jumper in "Normal" position
