It should be under /boot/grub2. I found out that it was missing by booting,
receiving a bare "grub>" prompt with nothing else, and spending time
doing web searches, learning way too much about EFI,
Fedora's GRUB puts the grub.cfg on the EFI System partition. It's non-standard. Path is /boot/efi/EFI/fedora/
and scratching my
head 'till my hair hurt. The grub directory is there, with grubenv and
themes, but no conf file.
Normal on Fedora.
No idea how grub.conf could have been deleted. I copied a couple large
directories from a server to the laptop (obviously not to /boot and not
as root) and then shut down. Next boot, no grub.conf.
Please don't use grub2-install which is obsolete on UEFI computers.
Docs I cited are consistent with this, including how to properly reinstall GRUB on UEFi.
