I did the Ctrl + R, did the disc utility ERASE and went back to the original menu and all I get now is a white screen with a ? flashing.  What can I do???



iMac, Mac OS X (10.7)

    Reboot from the recovery partition and install an OS from there.

    How do I reboot from the recovery partition?

    Install or Reinstall Lion/Mountain Lion from Scratch


    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.


    Boot to the Recovery HD:


    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.


    Erase the hard drive:


      1. Select Disk Utility from the main menu and click on the Continue button.


      2. After DU loads select your startup volume (usually Macintosh HD) from the

          left side list. Click on the Erase tab in the DU main window.


      3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on

            the Security button and set the Zero Data option to one-pass. Click on

          the Erase button and wait until the process has completed.


      4. Quit DU and return to the main menu.


    Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.


    Note: You will need an active Internet connection. I suggest using Ethernet if possible

                because it is three times faster than wireless.

    How do I reinstall Lion when all I'm getting is a flashing ??

  • Niel Level 10 (298,669 points)

    Restart to the recovery partition as Kappy described. You need to have run the Disk Utility from an alternate system to erase the internal one, and that system will contain a Mac OS X installer.

    How do I run the disk utility from an alternate system?

  • Niel Level 10 (298,669 points)

    If you previously got to it by pressing the Command and R keys at startup, do it again. This time, don't open any of the utilities; instead, run the installer when prompted.

    When I do the Command & R, I get the ? flashing. No choice of installing anything

  • Niel Level 10 (298,669 points)

    Restart with the Option key held down. If there's a recovery partition, click on it and press Enter. If not, you need an install DVD; phone Apple if you don't have one.


    If you see a screen with a padlock and text field, provide the computer's firmware password. If you don't know that, phone Apple.
