Hello there, after two days of reinstalling Mountain Lion I am convinced something is wrong, I am now on the screen with the X displaying and 20 minutes remaining for the last 9 hour and no movement. It all started when I tried to upgrade to Mavericks and the machine crashed so I had to do an internet recovery that took over a day and another 9 hr wait. I was on this same grey Linen screen for 8hrs and I decided to restart and now after 9 more hours I am not sure what to do. Please help I am new to MACS. This is on a MBP mid 2012 and its a clean install cause I lost all my data.
