I have a MacBook Air Mid-2011 and I'm stuck in an endless installation loop where it keeps taking me back to OS X Utilities after it's done installing. I boot to internet recovery (Command+Option+R), then I chose install Lion and after that a screen comes up that says "downloading additional components. your computer will restart automatically" and it does, but it takes me back to the OS X Utilities page. What can I do?!???!
