If your system is booting in UEFI mode (running "efibootmgr" shows boot entires), there's an extra file that needs to be updated that I don't think is clearly documented anywhere, nor is there a command to updated it. That is /boot/efi/EFI/fedora/grub.cfg. It searches for the /boot partition by UUID. To find the correct UUID, I believe this will work: - boot a Live image from USB - select Troubleshooting at the boot menu and choose Rescue - at the prompt, choose to mount the system - in the shell, run: chroot /mnt/sysimage - find the correct UUID with: lsblk -o UUID,MOUNTPOINT | grep ' /boot$' - edit /boot/efi/EFI/fedora/grub.cfg and put that UUID on the "search" line I'm not sure that this is clearly documented anywhere, and I don't think there's any command to update that file easily (unlike regenerating the main grub.cfg with "grub2-mkconfig -o /etc/grub2.cfg"). -- Chris Adams <linux(a)cmadams.net&gt; _______________________________________________ users mailing list -- users(a)lists.fedoraproject.org To unsubscribe send an email to users-leave(a)lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
