Thanks,
Actually, I am lost.
I am upgrading one of the systems on a multi-disks system.
1) I realized that one system is not efi, while the other ones are.
2) After I upgraded this system. I can boot it, but it is weird.
a) There was no update of the grub menu (I boot fc32, while the
invitation is still fc30)
b) grub2-mkconfig has not been run
c) grub2-mkconfig (manually) did not recognized by the booted system
except through set root='hd2,msdos3', but no menuentry for this
system.
I've exhausted my knowledge. I'll make some suggestions, but no
guarantees.
Check /etc/default/grub on the F32 system, and make sure that all the
entries are correct for the F32 system. It needs to have
GRUB_ENABLE_BLSCFG=true
somewhere in there so that boot loader snippets will work.
GRUB_ENABLE_BLSCFG=true is in /etc/default/grub by default to use the
new BLS boot loader standard, which as I understand it if this is active
then grub menus are not used, hence /boot/efi/EFI/fedora/grub.cfg would
never be updated on new kernel installs, as again as I understand it BLS
writes the boot loader rather than it being written by grub. I don't
like the menu display created by BLS as it is the same as the menus
created by grubby, which I also hated. Consequently I have
GRUB_ENABLE_BLSCFG=false in /etc/default/grub and I manually issue the
command grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg so that I get
the boot menu structure that I want.
regards,
Steve
Look in /boot/loader/entries/ on the F32 system, and make sure that
there is an entry for each of the F32 kernels that you have installed.
Go into /boot/efi/EFI/fedora/ and run
grub2-mkconfig -o grub.cfg
A reboot should now show F32 as a viable boot option, and as the
default.
