I think the root cause of the problem is that you have upgraded multiple
times, and somewhere along the way (maybe around the F25 timeframe), the
management of the rescue image and its grub entry got lost by the
release and testing teams, and never removed or upgraded. It is still
there and not getting cleaned up by any of the upgrades, but waay out of
date and missing more than a few critical bits now. This is probably
one of the casualties of allowing testing on VMs instead of real
machines and insufficient release acceptance criteria. So for your
situation, its dead, Jim.
You may be able to recover using the install media like you can in
Ubuntu or Debian or Slackware, but I had no luck with keeping the
filesystem contents intact using the default one-disk layout on Fedora
30. I probably didn't have the obscure document available on how to
actually do this, so YMMV of course.
Failing that and assuming that you don;t have a petabyte or so of LVM
content, it may be possible to mount the existing LVM volumes from the
install media, in order to copy off a backup of what you need to keep
undamaged, and reinstall from scratch.
So many things wrong with that...
1. The rescue images don't get updated automatically. You have to
delete the existing one and then a new will be created.
2. The default install is a separate filesystem for /home so even a full
reinstall won't damage your user files.
3. He doesn't actually have a problem right now, he's trying to plan
ahead in case something does happen in the future.
