Grub fails with unrecognized number
I just upgraded one of my computers from Fedora 29 to 30 and after that
grub doesn't work any more as it should. Now when I boot up I get
briefly the following message
Booting from Hard Disk...
.
error: ../../grub-core/kern/misc.c:465:unrecognized number.
then it boots the default kernel. I was expecting the grub menu.
Anybody knows what's going on?
Cheers
Robin
