    You logic is sound (as always). The only thing I can say is the BIOS should have the option to enable or disable secure boot (as shown in my screenshot). At this point I think the OP needs to contact Lenovo support and ask them directly. As you are aware, laptop manufacturers are well known for limiting what options are available in the BIOS for user configuration. Who knows, maybe the latest BIOS update might unhide that option?
    That is quite possible!

    A year ago we were on version 1511, upgrading to version 1607 may have caused this issue and you wouldn't be the first.

    Reset BIOS to factory setting won't hurt if you get <<false>> reading in powershell. You even have the solution in post # 14. Thanks to @Anibor.

    All the best,
    I have never heard of that.

    Neither had I, so I looked it up . . .

    Does Windows 10 change BIOS/ Cause boot problems

    Basically, the answer to the question says Windows 10 does not change any BIOS settings.

    Perhaps you have.

    I believe your answer is to turn CSM off (which is legacy support).
    Just remember, if you have installed W10 in Legacy, your system won't boot after making that change.

    Good work KB!

    It makes sense that the CSM parameter was causing this issue or disabling Secure Boot.

    Take care,
