Grub does not boot after kernel upgrade (secure boot disabled)
after performing a kernel upgrade, grub2 does not boot into Fedora 19 any more.
I had installed FC19 with secure boot disabled.
When I try to enable secure boot again from the BIOS, I probably wasn't able to sign either grub2 or the (new) kernel properly.
If I try to start the newest kernel with secureboot disabled, I am prompted with the error message:
Secure boot not enabled
alloc magic is broken at ...
whereas if I enable secureboot, I am requested to "Select an X509 certificate to enroll".
I can in fact still boot Win8 (both with and without secure boot), and fortunately can still boot the kernel prior to the upgrade (without secure boot, of course). I immediately set installonly_limit=0 in /etc/yum.conf , in order to avoid future kernel upgrades to clean that working kernel!
Available documentation on secureboot/UEFI/shim is not so clear ...
Any help will be deeply appreciated!
It might be a bug, possibly not related to secure boot. See https://bugzilla.redhat.com/show_bug.cgi?id=976768
