Hi,

 

Have you installed new hardware?

 

An invalid Secure Boot signature may be caused by malware, or BIOS corruption, or new hardware.

 

Tough to conclude the cause of your issue.

 

You can turn off Secure Boot using instructions at this (Link). Doing this will allow malware to run if you are infected.

 

Regards
