I was working on my unit when I was prompted to download a bios update. I was at a point where I could brake from my work so, I restarted my unit for the update after which, I could no longer access my unit. Almost 3 hours on the phone with Intel support he concluded that perhaps my system was corrupted and I should call the manufacturer of the unit. I have not received any paperwork to indicated who that might be and I am now dead on the water. As you know there are a number of vendors that sell these units with no info on who might be mine. I ordered my unit from Intel and are closed until Monday. By the way the box indicates that it was made in China.
Does the NUC turn on? Any lights on the NUC?
Can you access the bios?
If you have already opened a support case with Intel, then you should continue with them. Tell the support agent that you have an Intel NUC and that Intel is the manufacturer. Made in China means nothing unless you have a counterfeit product.
Do you by any chance remember what BIOS version you had before the update?
Please answer these questions.
From this link, download FN0039.CAP. Yes, I know it is older.
Format a usb stick that is at least 8GB as FAT32. Do this on another Windows PC. Not linux or MAC.
Put the FN0039.CAP file on the usb stick.
With the NUC off, insert the stick in one of the USB ports.
Power on the NUC by holding in the power for FOUR seconds. It should turn yellow. Release the button.
You should get a bios menu. If so, select F4 for bios recovery.
After the bios recovery, reboot the NUC. As soon as the NUC begins to reboot, start tapping on F2 to get into the bios.
Once in the bios, select F9 to reset defaults (assuming you have not made any custom settings).
Press F10 to save, and reboot.
Then NUC should boot normally.
So, your boot media is missing and/or you are network booting.
Was the bios recovery successful?
When you boot your NUC, F2 to the bios an see if your SSD is being seen and what your boot order is?
Ok, Boot to the bios with F2.
I do not have the same nuc as you, but these steps should be close.
Once in the bios, what is the bios revision now?
In the bios, select ADVANCED. Then select STORAGE. Is there an entry on m.2 sata? If so, what is it?
In the bios, select BOOT. Is UEFI checked or not? What is boot option 1 set to?
Well, the bios recovery did not work as you still have 0041, and you should have 0039.
Did you add the kingston drive, or did it come with your NUC?
Did you add the seagate drive, or did it come with your NUC?
Ok, I am assuming the kingston was the boot drive.
In the bios, under BOOT, it has a checkmark on UEFI boot. Does it make any mention of the boot order of the drives. Is the kingston in the first position of the boot order?
Ok, I am still thinking the bios update is what caused the problem.
Since you were unsuccessful at the bios recovery method, we will try this.
With the NUC off, insert the usb stick with the FN0039.CAP file on it.
Turn on the NUC and Immediately start tapping F7. When you get into the bios update screen, on the left side, you should be able to select the USB stick and then select the FN0039.CAP file. Proceed with the update process which will downgrade your bios to 0039.
Then, when the NUC reboots, begin tapping on F2. When in the bios, capture that bios string again.
Then, try to boot the NUC normally.
