I had the same problem. For me, I had to save the Secure Boot change, exit the BIOS completely, and then reboot back into BIOS before the installer finally recognized it. Let me know if that works.

You could also try clearing the TPM from the BIOS security menu, as that sometimes resolves Secure Boot detection issues.

Yeah, I had the same problem. For me, I had to save and exit the BIOS after enabling Secure Boot, not just enable it and continue booting. Good luck!

Agreed. You could also try clearing the TPM in your BIOS, as that sometimes resolves Secure Boot detection issues. Another option is to check if there's a BIOS update from Lenovo that specifically addresses Windows 11 compatibility.

Same here. Yeah, that's a good point. Also, make sure you save and exit the BIOS after changing those settings, not just backing out.

Agreed. Oh, and did you check if the disk partition style is GPT and not MBR? That'll block it too.

Agreed. I had the same problem. For me, it was the TPM. Even though it looked enabled, I had to clear the TPM in the BIOS before it would finally pass the check.

You could also try updating your BIOS to the latest version, as that sometimes resolves these Secure Boot validation issues. Another option is to double-check that your disk is using a GPT partition style and not MBR.
