+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.
