Turning off secure Boot worked. Microsoft and Boeing have the same low quality control standards.
Verifying shim SBAT data failed:

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

2024-09-04T21:44:47+00:00 Hmm, it seems the reg add made things worse, it didn't help and afterwards I uninstalled the August update, but due to the registry change the important part was not uninstalled. Shouldn't the order be: first uninstall August update, then run the reg add command?

But as you said I did them, but the command said 'Access denied', I did the BIOS turn off to turn pc on but the problem still stays.😐

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.
This might work.
