Latest Bios for Nuc

Quasio · ‎03-09-2025

Hello, after updating the Bios of my NUC6CAYH to version AY0076, neither UEFI Boot nor Legacy Boot recognize the hard drive, which is recognized by the Bios.  Secure boot is disabled. And of course before updating was working ok. Can anybody help me, please? Thank you very much.

I suggest you reinstall this BIOS again, but this time use the jumper-based BIOS Recovery process. Place the .BIO file in the root folder of a flash drive. This should be the only .BIO file on this flash drive.
Power off the NUC and then power it on again - holding the power button in for a full three seconds. Wait for the Power Button Menu to appear.
Once the Power Button Menu appears, press the F4 key to start the BIOS Recovery process.
Once the BIOS Recovery process says it is complete, power off and unplug the NUC from AC power for 5 minutes.
Power back on and use the F2 key to enter BIOS Setup.
Once there, press F9 to reset the BIOS configuration and then F10 to save this change and exit BIOS Setup.
Test to see if the system will boot.
Hope this helps,

Hi n_scott_pearson. No way. I tried as you said and I think every forms that it´s possible updating the bios and nothing. The boot doesn´t recognize the ssd. I would like to get the old version of bios... Anyway very many thanks for your attention and a cordial greeting.

Hi again. It´s working. After locate an old bios AY0065, downdating the bios and changing the boot to Legacy it´s ok. I don´t know really wich one had before. Thank you very much. All the best.

Hhmmm, you did reset the BIOS configuration after the BIOS Recovery operation, right? And you tried changing to Legacy Boot?

The release notes don't say anything about support for Legacy Boot being removed at any point between BIOS 65 and BIOS 76. Let me check with the old BIOS team and we'll see whether this happened...

Yes, after Bios Recovery and some time power off, I did the Bios reset with F9, F10 and star again, no ssd neither Legacy nor Uefi, I traied each one and no way a lot of attempts and after change the Bios to 65, only activate Legacy to recognize the ssd ok.
