dual boot on macbook pro 9,2 osx 10,9,1 and ubuntu 13,10 after an unrelated upgrade (to iMovie on osx) rEFInd no longer opens on re boot and i have no options on which os to boot? i tried to boot from the ubuntu 13,10 cd but it gets to a black screen and never runs the cd.
This happens sometimes when you do OS X updates (even if they seem unrelated, and especially if you try to upgrade your OS X to Mavericks). If you still have the binary files you used to install rEFInd try running the install.sh script again on OS X - there is no need to uninstall rEFInd first, just run the script again. That should fix your issue.
