I installed some kernels from source and then without uninstalling I deleted the source files. Now I can't remove those entries from my grub menu. I can remove them using grubby, but if I do grub2-mkconfig they come back. DNF cannot detect those kernels, so dnf remove doesn't work too.
It should be sufficient to remove all related files in /boot and in /lib/modules. grub2-mkconfig should be executed afterwards to generate the new grub configuration based on the files in ´/boot`.
Yes, you have to rm /boot/*<kernel-version-to-remove>* as the kernel files and maybe initrds were not placed by RPM but rather by a script which just copied those files there.
If you are unsure, it also might be a good idea to run yum reinstall $(rpm -qa kernel*) after you cleaned up your /boot directory. This should reinstall the kernels managed by Fedora.
