I've installed the latest refind to manage a ssd partitioned with OSX and Ubuntu. This has been working great and has been set up exactly how I wanted it until a recent dist-upgrade.
For some reason now my refind boot menu shows an option to boot fallback from EFI with an unknown_os icon. Selecting this option takes me into grub.
I've looked in my EFI directory which contains /EFI/bootx64.efi as well as bootx64.efi.grb. It also has the standard ubuntu and APPLE subdirectories containing the firmware.scap, grub, skim and mokmanager files.
Is there a safe way to remove the fallback entry from my boot menu as it was before?
