I know that the boot mechanism changed a bit for F30, but I'm not sure where to look to identify the cause of this problem. It doesn't seem to be the same issue as described in BZ 1652806. Post your /etc/default/grub file I'm willing to bet there's a line GRUB_SAVEDEFAULT=true If so, delete that line or comment it out and then run the usual grub2-mkconfig and directing the output to the proper grub.cfg path for your firmware type. The default that should be honored is found in the grubenv file, which (curiously) is found at the same path no matter your firmware type: /boot/efi/EFI/fedora/grubenv You can list its contents # grub2-editenv list And you can change it with #grub2-set-default <title of kernel> The title of the kernel is found in the /boot/loader/entries/*conf files - there is one file for each kernel. -- Chris Murphy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
