I like to check 'efibootmgr' inside the installer. Alternatively, you
can look at the NVRAM contents with evivars. (I don't have experience
yet with the newer efivarfs, but I think that's similar.) If you cannot
find the UEFI boot variables, then GRUB cannot either---and the setup
will be defective. It will not boot in UEFI.

Old GRUB boot sectors can make the boot experience even more confusing.

That's how all my equipment, which is up to a decade old, works but it's
always a wire act from USB creation to first boot.

I do not recommend Secure Boot for average Linux users. It tends to
create more problems and may not provide the security you expect.

Kind regards
