I've not had problems updating BIOS before, but my current BIOS is
DNKBLi7v.86A.0073.2021.0414.1709 and I've tried 3 times to load
DNKBLi7v.86A.0074.2021.0714.1836. The system reboots, but the new BIOS doesn't load. I don't know if anyone else has this problem, but I thought I'd let somebody know. My system is still working fine, so I'm not worried.
Try turning off "Secure Boot" in the bios, then save, reboot, and try updating the bios again.

Thanks for taking the time to reply. It is greatly appreciated.
I tried turning off Secure Boot, but that brought me to a BitLocker unlock screen and I don't have any code with which to unlock. I rebooted and then tried pressing F7 for BIOS update, but got a screen that frightened me because I realized I was out of my depth and I feared bricking my NUC. Maybe the next time they upgrade the BIOS, then the reboot will load the new BIOS as has happened every preceeding time.
Thanks again for trying to help me!
I've checked the BIOS update from version 0073 to 0074 on my NUC DN (the Secure Boot is enabled). I confirm your findings. The express BIOS update is not updating the BIOS after restarting the system. I've make two attempts: from Intel DSA and with DNKBLi7v.86A.0074.EB.msi file. Both attempts failed. So, this should be corrected by Intel.
Next I've downloaded the DNi70074.bio file to USB stick. With Secure Boot enabled, using the F7 update method, BIOS was updated to version 0074 successfully.
Thanks for verifying the problem with the BIOS not updating properly. (I'm glad it's not just me :-))
I'm working on an unrelated project that needs my attention, so I think I'll let Intel fix the issue rather than trying to put the BIOS on a USB stick since everything is working well with 0073. I'm glad to know that there is a workaround.
