**Subject: Can NOT get Win11 to install!!** So my PC meets all the other requir?

+1 Yeah, that's exactly it—the FX series isn't supported, so the security check will always fail.

+1 I had the same problem with an old Intel chip. The security requirement is a hard stop, so I had to upgrade the CPU.

You could also look into a registry edit workaround to bypass the CPU check, but it's not officially supported.

[NWRRu]

This. Before trying that, can you double-check if Secure Boot is actually enabled in your BIOS?

[785Oe39]

I had the same problem. My BIOS said Secure Boot was enabled, but the installer still failed until I also enabled TPM 2.0.

[jfbe9888]

Same here. This happened to me. I had to go back into the BIOS and actually switch my drive from MBR to GPT before Secure Boot would work right.

[700hnhvuk]

Yeah, the AMD FX chips are definitely the issue because they don't have the required TPM 2.0 support.

[nk1690278981]

Same here. Agreed, that CPU is the main blocker. A small tip: you could check if a clean install from USB bypasses some checks, but it'll likely still fail on the CPU. Good luck!

This. Yeah, that's the issue. One extra thing: double-check your BIOS for TPM 2.0 and Secure Boot settings just in case, but the CPU is probably a dead end.

I had the same problem with an old Ryzen chip. The CPU requirement is really strict, and no amount of BIOS tweaking got around it for me. Let me know if that works.
