i upgraded from F27 to F30.
I have this new BLS boot loader spec turned on.
i have a 2007 dell PC so i assume it has a BIOS not UEFI
At boottime i get a couple of errors ‘boot image not found’ but it still boots up.
rpms for 5.0.13-300.fc30 and 4.18.19-100.fc27 are installed.
At boot, I do not get the usual screen to select from the various kernel versions.
kernel 4 gets selected automatically.
grubby output here
