I erased everything on my MacBook air hard drive by using disk utility and shut down my notebook but when I turned it on, it showed a disk with a big question mark. Then tried starting it up in disk utility and startup manager but they both brought me to this screen that need wifi connection. When I looked for my connection, it was missing along with all the others except for one connection that is someone else's. I want to know if I can use my 1 tb hard drive and put disk utility and open it when I start up my MacBook air to reinstall Mac os x lion.

 

Thanks,

Lucas

    Make sure you have a WPA or WPA2 WLAN and know your WPA security key. Now, restart your Mac while holding  Command+Option+R until you see a spinning globe appear along with a message about the recovery mode.

    Okay, so thanks a lot for telling me that. I had a wep network and I just changed it to wpa but when I clicked on the globe, a exclamatio mark appeared on the globe and below it it says apple.com/support and below that it says -2100F. What should I do now?

    It's unlikely that you erased the recovery partition with Disk Utility since it isn't visible in Disk Utility.

    Turn your MBA off.

    Turn the MBA on.

    When you hear the tone from the speakers press and hold the Option key.

    If the recovery partition is still there it should appear on the screen as a bootable drive.

    Select it and hit return.

    I believe I did erase the recovery drive :(. It's asking me to use network recovery but this time the error is -2105F, not -2100F. What should I do now? Can I somehow format my 1 tb external hard drive into the drive that my MacBook air is running on and then I can fix the rest because that way I'll have disk utility.

    Thanks,
