It's basically my rEFInd folder zipped. Configure the refind.conf file to use manual boot stanzas. These are hardcoded (in the config file, much like a grub file in linux) options so the name of the volume of your OS X cannot be changed without changing the configuration file. If you fail at this and change the volume name without updating the .conf file, that particular boot option will not be bootable anymore. But since you'll have two OS X's you can force Apple's bootmenu with Alt at the startup, boot the other volume and fix the .conf file.
