My rule is: Never (ever!) use the .EXE files to install BIOS updates. This method seems to be badly broken and often causes this phenomenon. Use the F7 method (using the .BIO file).
Ok, to get this going again, I would start by doing a CMOS clear. See here for instructions: Intel NUC Clearing CMOS.
If this doesn't work, you should next reinstall the BIOS using the Recovery method. This requires that you download the .BIO file. See here for instructions on how to do BIOS Recovery: Intel NUC BIOS Recovery Update Instructions.
Hope this helps,
Thanks. Will keep that in mind for the future.
Unfortunately, nope/neither. Nothing changed by moving the CMOS jumper, and with the .BIO file on USB, the thumb drive lights up when the power cord is connected, and again when the power button is pressed, but I've tried a few times with both front ports and can't get the power button menu to appear or anything else to display. The timing's a little faster (maybe 8/3?) but it's still cycling on and off in a loop the moment I press the power button.
Make sure that the USB flash stick is formatted using the FAT32 file system and that it is done from a Windows-based PC. Linux cannot be used; its FAT filesystems are not 100% compatible. Further, if the USB flash stick has previously been formatted to support Linux boot, you likely need to fully reformat it (i.e. without using the QUICK option).
Getting to the power button menu is pretty exacting. You have to hold the power button down for pretty close to exactly 3 seconds. If you hold it too long, the hardware-based power off (which occurs at 4 seconds) will kick in. Keep trying.
Your other alternative (and perhaps last resort) is to use the jumper method.
You can also try this as a last resort:
- Remove CMOS battery, hold down power button then reconnect
- plug the nuc power adapter
- plug in headphones
- press and hold power button, you will hear three loud(!) beeps, release the power button just after the third beep
- you will have the option to upgrade/flash bios aswell as other settings.
