Dualbooting with Linux

#Method A: OpenLinuxBoot

OpenCore now includes a driver OpenLinuxBoot.efi which should make dualbooting with Linux much easier.

The steps to using it are:

1. Install Linux as you normally would e.g. by booting from an .iso image burnt to a removable USB drive - OpenLinuxBoot.efi is not involved in this stage
2. Add OpenLinuxBoot.efi and ext4_x64.efi to your config.plist Drivers section
3. Make sure RequestBootVarRouting and LauncherOption are enabled in config.plist; it is also recommended to enable HideAuxiliary in order to hide older Linux kernels except when you need to see them (which you would do by pressing SPACE to show auxiliary entries in the OpenCore boot menu)
4. Reboot into OpenCore, installed Linux should now just appear
5. Never use Grub again

If you previously used method B or C below, you will need to remove those settings in order not to see your Linux distro twice in the OpenCore boot menu.

For further information on how OpenLinuxBoot works and additional trouble-shooting guidance, see the OpenLinuxBoot section in OpenCore’s Configuration.pdf document.
