I am using dual boot with Ubuntu & Windows 10.
Since I try to upgrade to Kernel 5.x, I get boot problems (cannot boot 5.x: Couldn't get UEFI db list)
The answer seems to be to enable secure boot. However, I can't enable it in bios - I get the message that I have to create a platform key (PK) first. How does one create that?
Here is a screenshot:

Secure Boot Modeare two options,StandardandCustom. It was set onStandard. There is another option calledSecure Boot Supportwhich is disabled. When I try to enable it, I get the message from above. – Adam Jul 17 '19 at 16:42
