booting to my main hard drive. After using Onyx, I restarted my MBA and it booted to the recovery partition. Now I am not a pro with all this so because this is the first time it has happened since I have owned a Mac. I got on my Windows machine and looked up some solutions, everything I tried didn't work. So, I had to a fresh install of Mountain Lion...which I will say that I guess it came at the best time because I was going to do a fresh install of Maverick's when it's released anyway, so only a few more days. My S.M.A.R.T. Status says the drive is fine (Thank God!), so I am assuming Onyx messed something up, which it never had before. Please, leave me some suggestions on what to do if this were to happen again and if Onyx can cause this. Thank You in advance!
