    UEFI Secure Boot - Greyed out - Disabled

    UEFI with secure boot disabled

    Hi.
    Reading on the Lenovo site:
    How to boot to Legacy device or system configured with Microsoft Windows 7 (32-bit or 64-bit) or Windows 8 (32-bit) - ThinkPad, ThinkCentre, ThinkStation, IdeaCentre
    So my question would be, what have you done to the system, that has disabled Secure Boot?

    EDIT: Perhaps you could just go into the BIOS and set it to defaults. But if you have installed a Legacy (MBR) version of W10, or upgraded a version of W7 to W10, you will not be able to boot the OS with Secure Boot turned on.
