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
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
Dave, the registry change works only if you make it BEFORE applying the august update, for example before restarting after update. After that SBAT is already changed. I suppose it is a change in the UEFI itself, because I cannot boot a Ventoy flash drive even if the hard disk is cleaned and deinitialized (diskpart, clean all)

There are some workarounds in the link.
Hi, Steve
Enter BIOS/UEFI, set a password for the supervisor, this should enable the option to disable secure boot.
I have the same problem
If you are using a MSI computer, press delete while the PC is starting, then a menu will pop up. Then open "advanced" and find Secuity. A "secure boot" is there and disable it. Does it works? works for me at least
