Has anyone else hit a wall with Secure Boot during the Win11 upgrade? My PC meets all the other requirements, but the PC Health Check app keeps failing on Secure Boot. In my BIOS (UEFI), it's enabled, but the TPM check still says it's unsupported. I'm getting the "This PC can't run Windows 11" error with no helpful details. Is there a specific setting I might be missing, or is it a motherboard compatibility issue?
You could also try switching from CSM/Legacy Boot to UEFI mode in your BIOS, as that sometimes resolves the Secure Boot conflict. Let me know if that works.
Can confirm. I had the same problem. For me, clearing the TPM in BIOS didn't work until I also disabled Secure Boot, saved, rebooted, and then re-enabled it.
