Sorry, my mistake. I thought this one also referred to Fedora 18. The main
I had was the UEFI boot order problem mentioned below. This page doesn't
me how to use efibootmgr to fix that.

Well in my case, reinstalling grub2-efi caused GRUB2 to stop reading the
configuration file from /boot/grub2/grub.cfg and to start reading from
/boot/efi/EFI/fedora/grub.cfg again. I didn't have to re-run grub2-mkconfig
because the configuration file was already built during the last kernel
update. I haven't tried booting Windows from my GRUB menu since this
fix, but I suspect it will work again, too. With the grub2-install GRUB, it
couldn't find Windows because it wasn't looking in the EFI partition.

Yes, it seems that any time I touch my firmware configuration ("BIOS
settings") or interrupt the boot sequence to boot Windows (after I've
managed to put Fedora first), the boot order resets to Windows first.
It may not be Windows doing it. I cannot move Fedora to the top of
the list using the "BIOS settings", I need to use efibootmgr for that.
