As the title explains I’m confused as to what the correct boot order is between the shim.efi and shimx64.efi files. I tried both combinations but it doesn’t seem to change anything, except that with the shimx64.efi file placed first maybe the boot is just a second faster (but that could be just my impression).
shim.efi and shimx64.efi are actually the same file, so it doesn’t matter. Just use one of them and ignore the other.
Thank you for the clarification!
