It may be that you have "Secure Boot" enabled. You can tell if secure boot is enabled by running MSINFO32. If it is, disable it in the bios, and try the update again.
If you are still unable to update the bios, you can put the .bio file on a fat32 formatted usb stick (8gb or more), boot with F7, and install the bios friom the stick.
Thank you Al Hill and Alberto, for your responses to my queries and my sincere apologies for tardy reply. I think I gave up, forgot I even posted the question and so never returned to see if anyone had responded. I have just gone around the same merry-go-round with Intel Driver & Support BIOS download yet again.
Al Hill, I'm not a tech person, so I need some help to understand your fix to the problem. How do I "run MSINFO32" to see if I have "Secure Boot" enabled? Would you mind providing step by step instructions please? I can use a handful of Microsoft 365 apps and can surf the internet, but that's about the limits of my computer skills/ knowledge. That said, I'm keen to learn.
Try to update BIOS, using BIOS Recovery from the Power button Menu method. Follow those steps:
- Prepare USB stick fully formatted to FAT32 (disable quick format option during format). Format your USB on Windows machine (rather than Linux or MAC). Save the Bios file BN0083.bio on this stick and insert it into front USB slot with amber color (NUC shall be OFF). You may use also one of the rear USB ports (do not use front blue USB port, since sometime the USB stick is not recognized during boot process).
- Press and hold Power Button for about 3 seconds. Count 1001, 1002, 1003,1004. Release the Power Button. NUC should reboot into Power Button Menu. You should release the Power Button before 4-sec shut down override or when the Power Button LED changes color from blue to amber.
- Press F4 and the recovery shall start (it can take up to 30 seconds for messages to appear on the screen).
- When the recovery finishes, press on Power Button and hold it, until NUC switches OFF. Pull out the power cord. Remove the USB stick.
- Replace the power cord and press Power Button to switch the computer to ON.
- While you see the Intel NUC logo, enter Bios setting by pressing F2 during boot process.
- Press F9(followed by "Y"), to set Bios to default settings. Press F10 (followed by "Y"), to save the settings and exit to O.S. Let the NUC fully reboot.
- If before update, you have customized bios settings, you can enter again to Bios setting to change the necessary settings.
Thanks Leon (and my apologies for double posting), I will try your method later in the week and let you know how I get on.
Ps, Although I'm pretty good at following instructions and yours seem very clear, is there any chance (if I stuff it up) that I cause problems for my computer functioning? I'm a little apprehensive venturing into the strange BIOS world - lol!
Every update may go wrong. But to update BIOS using BIOS Recovery method is more safe than the update using .msi file with IDSA. It is little more complicated, because you need to use the USB flash memory stick. I did such update lot of times and never got problem.
