All bootable devices failed secure boot verification

Question

F2 on start up gets me to settings where I've turned off Secure Boot but when it starts up again after I exit I get the message No bootable devices found. What do I try now please?

Did you accidentally switch from UEFI to Legacy boot mode (or vice versa) while fiddling with Secure Boot.  Some operating systems can install in either Legacy or UEFI mode, but after they're installed, they can only be booted if the system is set up in the mode they're expecting.

No, it's still in UEFI mode
