Trying to boot from a usb stick In win 10 I get the message "Verifying shim SBAT data failed: Security Policy ViolationSomething has gone seriously wrong: SBAT self-check failed: Security Policy Violation" Can someone help me resolve it? Is this from the latest windows update?

This seems to have started right after a win update but I'm not sure if it's a coincident or not. Thanks for any help

    Yes. Another person sent me instructions that have both OS systems working.

    Here are his instructions:

    Amruth DD has replied to the question Verifying shim SBAT data failed: that you are following in Microsoft Support Community.
    Try pressing the F2 key repeatedly immediately after turning on the power. This should open the BIOS menu. Once the BIOS menu opens, navigate to the security/boot option (it may vary depending on the machine) and locate the "Secure Boot" option. Change it to "disabled". Save the changes.<br><br><br><br>This might work.

    I am thankful for your reply. I had figured out how to start the computer, but I am not able to figure out how to disable the “secure boot” feature. Do you have those instructions? Thank you! Respectfully, David

    1. Press the power key and keep pressing ESC button till BIOS related menu appears.
    2. [In hp] press F9 or BIOS menu and select Windows UEFI to start Windows Operating System .

    Note: You have to do these 2 steps every time to start your Windows OS.

    Solution: a) Disable Secure Boot in Windows / Ubuntu.
