Scary error screen I saw

After yesterday's Tumbleweed update, my laptop was rendered unbootable. It
displayed a scary Windows-style blue error screen saying that the system was
broken. There is no Windows partition on this machine, so it must be some kind
of backup EFI error screen or something.

I was able to boot into the EFI shell of a recovery USB flash disk I had lying
around and then boot into my openSUSE TW OS by doing the following in the EFI
shell

fs0:
cd EFI
cd opensuse
grubX64.efi

And then I saw the normal openSUSE kernel chooser boot manager and was able to
boot normally. So this bootloader works just fine. However for some reason this
bootloader is no longer automatically used anymore after the update.
