Hello Eric. Thanks for joining the Intel Community.
We have seems compatibility issues with the SSD you are using, however customers were able to resolved this issue by updating the BIOS to version 0027 and then rolling back to BIOS version 0021.
Please check the following thread Is D54250WYK (i5 Haswell) compatible with Samsung 840 EVO 1TB mSATA Internal SSD?
I would recommend you to follow that procedure. If the issue persisted, please try using a different SSD.
Finally, if none of these suggestions fix this problem, please contact our Warranty team in order to get your product replace. The following link will show you the contact information Contact Support or submit a web ticket at the following URL Service Request Email
Thanks Sylvia. Let me try. Without being able to install the OS I have no way of downloading the firmware. When I entered the BIOS settings screen via F2, there was no network connectivity even though I connected the NUC via a cat 5 cable and the network lights were blinking.
Even though I had BIOS version 0030, Intel NUC was still able to recognize the Samsung 850 EVO 2.5" SATA (not mSATA) SSD. The issue was that it sometimes couldn't detect the DVD drive and couldn't boot from the Windows 8.1 DVD.
I did two things to get it fixed:
- Downgraded to 0021 didn't work. I upgraded to the latest BIOS 0037. Still didn't work.
- I have had the external DVD drive for almost 10 years now. I swapped the USB cable that connected the DVD drive to NUC with another one, possibly from one of the devices I got a few years ago.
Then I could boot from the DVD and installed Windows 8.1 on the 850 EVO SSD.
I tried using that other cable when I had the BIOS version 0030 but it didn't work. So the combination of using the latest BIOS and another USB cable fixed the issue.
I called Intel phone support and waited for something like 5 minutes to talk to a real person! She showed me how to flash the BIOS even without an OS installed: Intel® NUC Boards and Kits — BIOS Recovery Update Instructions.
In case you have the same issue you can try the above to flash the BIOS.
Thanks for the information Eric.
