Has anyone else hit a wall trying to upgrade to Windows 11 because of Secure Boo?

+1 Yeah, that's a common snag. One extra tip: after converting to GPT, double-check that CSM/Legacy Boot is disabled in your BIOS, as that can sometimes block the upgrade too.

Yeah, I had the same problem. I had to actually disable and then re-enable Secure Boot in my BIOS before the checker finally recognized it.

This. Agreed, that toggle trick often works. Also, make sure you save and exit the BIOS properly—sometimes a quick restart isn't enough.

You could also try clearing the TPM from your security settings in Windows, as that sometimes resolves the conflict.

Yeah, clearing the TPM is a good call. Also, double-check that your BIOS is set to UEFI mode and not Legacy/CSM, as that can trip up the check.

+1 I had the same problem. For me, disabling the CSM support completely in the BIOS, not just enabling Secure Boot, finally got it to pass the check.

Yeah, after disabling CSM did you also remember to save the changes and fully restart before running the check again?

Also, are you running the latest version of the PC Health Check app, as older versions sometimes gave false negatives? Good luck!

Yeah, and sometimes a quick reboot after enabling it in the BIOS helps the setting fully register with Windows. Let me know if that works.
