I am also having the same error :

That’s exactly the same issue that I’m experiencing here with a Fedora 30 installed on a UEFI device!

/boot: ext4
/boot/efi: fat16

have to mention that this issue is not causing any problem while the system is booting (i.e. it is ignored while booting but just take a few seconds to show up and then pass…).

Fixed , the fix is on the fedora main repo, just update your system or:

sudo dnf update grub2\*
