When UEFI Secure Boot is enabled, which it should be if available, especially on a system with Window on it, you need the distro signed shim.efi and grubx64.efi on the EFI system partition. If you use grub-install the signed copy is wiped out, and the system won't boot until you disable Secure Boot.
So in a UEFI Secure Boot world, grub-install (and grub2-install) is obsolete.
This bug is still annoying, and I wonder if it should be a blocker bug. https://bugzilla.redhat.com/show_bug.cgi?id=1170245
my system originally came with windows 10. I seem to recall that from what I read, you needed to disable secure boot to install linux & grub..
