grub2-install does not apply on UEFI systems at all, it should not be used. Instead you reinstall shim and grub2-efi packages.
thanks, I got some other replies that mentioned efibootmgr, and that did the trick. my default grub was ubuntu, but I wanted it to be fedora. efibootmgr -v showed default 0004, which is ubuntu. once I changed that via: # efibootmgr -o 0002,0004 0002 is fedora. When I rebooted, it used the grub.cfg from fedora and all is well.
