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

    Hi, I am Dave, I will help you with this.

    Are you dual booting Windows with Linux?

    If you are, this is caused by a reported problem in the August update if you can get into Windows, either uninstall the August update, or open Command Prompt as administrator and run this command, then press Enter.

    reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecureBoot\SBAT /v OptOut /d 1 /t REG_DWORD

    Then close Command Prompt

    Tried this but didn't solve the problem. I was trying to boot into elementaryOS from my bootable USB.
