Attempted to do a fresh install of Ubuntu by following the procedure found here: Clean install Ubuntu on a dual boot with Windows
I assumed that the fact that it was for Vista instead of OS X was inconsequential. My base OS is Yosemite.
Now when rEFInd starts up, I still see the option for OS X and Ubuntu but no option for installing Ubuntu.
When I click the Ubuntu option it says "error: no such partition. entering recovery mode"
Any ideas on how to resolve this? Any and all input would be greatly appreciated!
UPDATE:
I attempted to start up GParted again to see if I missed something and now rEFInd isn't seeing it either? Don't know if this is useful info? Does Gparted depend on the presence of Ubuntu?
FURTHER UPDATE:
1) Base OS: Yosemite
2) What media device you are installing Ubuntu from: DVD+R
3) Your method before it stopped working: Not sure exactly what you mean by method. I was attempting to get my WiFi working (It works for OS X but didn't work for Ubuntu, GParted, or Tails. but I'll cross that bridge later). I used rEFInd to load it, and used GParted to delete it.

Please refer to my answer to another question involving similar difficulties. The method is the exact same, except you should skip step 4 and use the Ubuntu ISO instead.
Before attempting anything though, remove all traces of your previous failed installation attempts from the Mac.
