My MPC will not boot up, I took it to Genius Bar in San Diego, and he showed me how to reinstall 10.7 OS without erasing Data.


I started the Reinstall process, but when signed in with my Apple ID, I got a message that I needed to Login with the Users ID who purchased 10.7


I bought my MBC with 10.7 preinstalled


Does anyone have an idea what is happening??



MacBook Pro (15-inch Early 2011), Mac OS X (10.7.5), Reinstall 10.7.5

    If the Genius Bar person showed you by using the App Store and your MBP came preinstalled with Lion, they showed you incorrectly.


    If you restart your system using Command+R+Option keys and keep them pressed down until you see a white screen with a spinning globe, you will be booting into Apple's servers and their Recovery HD so you can download and reinstall your factory assigned version of Lion. This process is called OS X Internet Recovery.


    For example, my MBP Retina came preinsalled with Lion 10.7.4. When I use the process above, 10.7.4 gets downloaded and reinstalled.

    Addition to my reply.


    If the Genuis Bar person showed you by restarting and using the Command+R keys, that should also work. If I want to go back to the factory OS, then my previous post will do that.


    In any case, always back up your system before you reinstall OS X.
