    I was given a Thunderbolt 15" Macbook Pro with missing shift keys as a broken project to do with as I wish.

    Now, the machine powers on, but it won't boot OSX.

    It goes through these steps:

    1. White screen for about 30 seconds
    2. Black Windows error recovery screen offering to Launch Startup Repair or Start Windows Normally

    Launching Repairs leads to "windows loading files"
    Then a Safe Mode looking repair utility pops up for Startup Repair

    "Your computer was unable to start"

    It tries doing this for a few minutes, then says it can't auto fix.

    Computer shuts off.

    Start again and at the black screen choose normal startus, computer never goes past the "starting windows" screen.


    Now, I'd like to put this thing back to OSX, but I don't know where to start.

    Any advice from you guys and gals?

    if you know the what OS came with it, download and install it. I will get flak here for the suggestion, but torrent it. Its simple, you are using the same OS that came with it, thus its legal, you just dont have the copy anymore

    Aside that, the install procedure is pretty simple, either a USB drive or a DVD should work

    if you really dont know how to proceed, go to an apple store and ask them to reinstall the OS

    Why not go into the disk utility from boot, format the drive, reboot, hold cmmd shift r and do an internet recovery? It will reinstall ML from the internet and be good as new

    because you can actually remove the recovery partition

    but OP give it a try, just that dont press cmd+shift+r, just press alt/option and see what you have in there
