States that the Fedora version is setup for the Fedora signed version, but the grub2-install then would try to install and unsigned version, and then if the secure boot was turned back on, it would then fail to boot the signed kernels?? But I'm trying to get it to create an EFI on a separate USB flash, so not sure how that would effect the EFI booting of the hard disk?? Seen similar stuff on Syslinux list about work on getting EFI support, and that has been going on for years. 6.03 of syslinux is still the latest full release going back to 2014, but the 6.04 has work done, but doesn't seem to be ready for prime time. More to look at, but less hope of finding a easy/simple solution. Just downloaded and build 3 new kernels from kernel.org, and with the regular (non EFI) they all work just fine.
