Secure Boot violation - Invalid signature detected

HP 411-a000na
Microsoft Windows 10 (64-bit)

Keep getting black screen with red box saying - Secure Boot violation - Invalid signature detected. check secure boot policy in setup. Then when restarting and entering the BIOS and choosing 'Apply defaults and Exit' everything starts OK until the next time. Any help would be appreciated, thanks

@DG52,

 

Welcome to the HP Support Community!

 

I recommend you disable secure boot in BIOS and check whether the issue is resolved.

 

Follow the steps in the below article to disable secure boot.

If you continue facing the issue, then update the BIOS following the steps in the below article.
