    These days when kernels are installed Fedora runs grubby to build
    the Grub boot menus. I've never liked the format of those menus so
    being UEFI rather than legacy bios I always manually run sudo
    grub2-mkconfig -o /boot/grub2/grub.cfg. Grub2-install is never used
    on uefi systems it is only ever used on legacy bios systems.
    Check /boot/efi/EFI/fedora, there should be a grub.cfg there that
    loads /boot/grub2/grub.cfg which will then load the grub menus at
    boot, that menu should then have all kernels installed. Also check
    /etc/default/grub, that file should have a line in it to supply the
    kernel options to be used at boot which should contain the options
    to blacklist nouveau if you are using nvidia drivers.
    
    regards,
    Steve
