Agreed. Yeah, and after you enable those, you might also need to switch your boot drive from Legacy/CSM to UEFI mode in the BIOS.

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?

This. Yeah, and make sure Secure Boot is also enabled in your BIOS, that one gets people all the time.
