    Hi there,

     

    When you boot from your USB to reinstall. Try opening the Disk Util and running the diagnostics on your Hard Drive (well SDD drive)...

     

    Run also a hardware test to make sure everything is fine (what you have may be a wrond HD or RAM that will need replacing). Try this: http://support.apple.com/kb/HT1509

     

    If everything is ok then USB drive you are using may be to blame. Try creating a new one. You can ask a friend with a Mac to create one for you or go to an Apple store where they will reinstal the original OS.

    I try restarting MacBook air holding down D.to run a diagnose on my hardwares but nottin happen, I try for 2 days and nottin happen, so that helped me move forward and reset the nvram by pressing option - command - p - r - untill you hear startup sound a secound time, and that did the trick for me. After it restarted it let me install mountain lion , I'm so happy.
