Interesting. UEFI systems with GRUB consider ls -l considers -l an
invalid filename so I get an error. But on BIOS systems, this command
does work.

Anyway, if you find Fedora netinstall or DVD media, and add boot
parameter 'rescue' (without the quotes) then you'll get a rescue
interface. Accept all the defaults for each page, and then at the end
when you get the prompt do

# chroot /mnt/sysimage
# grub2-install /dev/sdX     ## where X is the letter designation for your drive
# grub2-mkconfig -o /boot/grub2/grub.cfg

This installs GRUBs parts, and will also create a new grub.cfg. The
old grub.cfg would probably work so it's possible you could skip
creating a new one.
