So back in 2011 I bought a new macbook pro, after a year and half it randomly stopped working. Whenever I turned it on, all it did was stay in the apple logo with the little circle spinning below. Then I tried cleaning the hard drive and doing a fresh install of the OS but it never worked. I took it to the apple store and they told me it was the ram. I ended up putting the mac away for some time and just took it out now. I installed new ram but cant install any OS on it. After booting recovery mode and cleaning the HD I installed OS X Lion from a dvd and from the internet recovery mode, both were unsuccessful. The installation seems to go well at the beginning with the timer going from 1hr down to 0s, but then it just restarts back to 1hr with the bar still fully blue. I thought maybe it takes forever so I decided to leave it overnight one day and the next morning it was still the same. I only have access to the recovery mode options and have verified and repair the HD countless times with no errors. I have spent the last 3 days trying to install an OS and installation always fails.
