Since the BIOS version 0061 is not listed as supported by that NUC, please install version 0058 to try to fix the problem.
Even though the problem seems to be related to the NUC itself, for testing purposes, do you have the option to test it with a different hard drive/SSD?
Did the NUC work fine before?
On the following link you will find the information of how to d a clear CMOS battery on the NUC:
If after trying those steps the problem remains, then a replacement of the NUC will be the next thing to do, please let me know if you are interested in that option.
Any further questions, please let me know.
When it was installed Bios version 0061 was listed as the latest on Intel's download page for this PC. It has since been withdrawn. I've been able to get to the bios by disassembling the NUC and unplugging the CMOS battery connector for about 10 minutes. When I re-assembled it and booted with the jumper in normal mode I was able to F2 into the bios and install version 0058. Hopefully, this will keep the problem from cropping back up.
