You could also try creating a fresh Windows 11 USB installer using Microsoft's Media Creation Tool, as sometimes the upgrade files get corrupted. Let me know if that works.

+1 Did you double-check that Secure Boot is enabled in your BIOS too?

Same here. You could also try creating a fresh Windows 11 installation USB and doing a clean install instead of the upgrade.

Yeah, that clean install tip is solid. One extra thing: double-check that Secure Boot is enabled in your BIOS too, it's a common trip-up.

Agreed. Also, when you're in the BIOS, make sure your drive is using GPT and not MBR for its partition style. Hope that helps.

Same here. I had the same problem. I had to manually enable Secure Boot in the BIOS, even though TPM was on, before the installer would finally accept my PC. Good luck!

+1 Yeah, same thing happened to me. A quick tip: after enabling Secure Boot, you might also need to switch your BIOS from CSM/Legacy to UEFI mode.

Oh, and did you double-check that the TPM is actually enabled and not just present?
