At a Genius Bar appointment yesterday, we determined that I needed to go to Mountain Lion from Lion. I purchased Mountain Lion at the Bar, and paused the install so that I could resume from home. Now I can't find it to resume. Not in Downloads. ?????

Question

When I upgraded to Lion, my Parallels stopped working and I got a Bootcamp error message.  It had worked fine for the prior year.  I upgraded to Parallels 7.  No luck. At the Genius Bar, the Genius uninstalled Bootcamp.  No luck.  I still get "The Boot Camp partition /dev/diskOs4 used by Hard Drive 1 is missing."
Another Genius suggested upgrading to Mountain Lion.  While at the Bar, I purchased Mountain Lion and then we paused the install so that I could resume it at home.  Once I got home, I can't find the Mountain Lion installer to resume.  It's not in the Downloads file.  Any clue?
My business programs all run on Windows, so I have to get it operating.  The Genius Bar isn't much help.  Does anyone know how to get Mountain Lion installed?  How to get Parallels working?

Answer 1

The "Geniuses" (and I use that word in sarcasm) at the Bar are lying to you. Upgrading from Lion to Mt Lion will not fix whatever problems you are having. In fact it will most likely make them worse.
If you want to try installing Mt Lion to fix the problems you are having you will need to open the Mac App Store link in your Dock, Login to your Apple ID account for the MAS and go to your Purchases area. Mt Lion should be in there and you will be able to do a proper download. Once you either set your Mac into sleep or shut down and then left the internet connection at the Bar all record of that download was lost. So you will need to restart it again from the beginning, like described above.
Good Luck
