At the grub prompt if you type set you should see either config_directory= and prefix= to show where it's looking for the grub.cfg. > > https://bugzilla.kernel.org/show_bug.cgi?id=73761 > https://bugzilla.redhat.com/show_bug.cgi?id=1085957 I'm not familiar with this usage: efibootmgr -B -b 0 If 0 is the same as 0000 then that seems to ask for the removal of a fixed entry: the DVD in CSM-BIOS mode (?) which I wouldn't expect to work, ever. But then it also shouldn't crash the kernel.

It would probably have to take some command line arguments. Something that properly deals with restoring shim, grub, grub.cfg, and NVRAM would be nice. But the NVRAM part might be a rat hole, seeing as some of the manufacturer NVRAM behaviors are pretty icky. And on top of that don't seem to have a good way for users to reset/wipe it. It's something I think the UEFI Forum ought to put in the standard and require it.
