**Subject: Windows 11 upgrade is a NIGHTMARE on my ThinkCentre M710** Okay, I'm?

Yeah, that's a solid suggestion. A quick tip: before you do, double-check that Secure Boot and TPM 2.0 are definitely enabled in your BIOS, as Lenovo sometimes has them off by default.

Same here. Agreed, and also try temporarily disabling any third-party antivirus during the upgrade process—it can sometimes block the installer. Let me know if that works.

Yeah, that's a solid tip. Also, double-check your BIOS settings to make sure TPM and Secure Boot are actually enabled, not just detected. Good luck!

Agreed. You could also try using the official Microsoft Media Creation Tool to do a clean install instead of an upgrade.

I had the same problem. I ended up needing to enable TPM and Secure Boot in the BIOS on my own Lenovo, even though the tool didn't say that.

Can confirm. This happened to me too. The health check tool was useless, but manually updating my BIOS from Lenovo's website finally got it to pass. Hope that helps.
