Just a heads up that this can be an issue, but I'm not sure how common it is. It applies to BIOS (not UEFI) firmware, and for systems that originally had Fedora 20 or older installed and also never had 'grub2-install' issued since then. Therefore it can be prevented just by running 'grub2-install' before commencing the Fedora 30 upgrade.

It's worth going through all the Common Bugs.
I am not entirely sure about this issue and now I have read all the posts about it and this Grub 'lesson' is just not getting into me.
So far the upgrade went fine as usual in my case. And now why I am replying here. My legacy boot has Grub and instead of booting into the newest Fedora 30 kernel it boots by default into an older one from Fedora 29. I never saw this before. So I have to catch up before the Grub prompt automatically selects the second kernel in the boot menu.
Anybody experiencing this?
