I have a 2008 Macbook Pro and I had OS X Snow Leopard 10.6.8. I went to the mac app store and started downloading OS X 10.9 the night before. The next day when I power up my Macbook Pro, I see the apple logo , the prohibited sign and a folder with a question mark. What do I do ? I still have my OS X 10.6 install disk if it means anything.

    Erase the drive and reinstall Snow Leopard.

     

    Clean Install of Snow Leopard

     

    Be sure to make a backup first because the following procedure will erase

    the drive and everything on it.

     

         1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came

             with your computer.  Insert the disc into the optical drive and restart the computer.

             After the chime press and hold down the  "C" key.  Release the key when you see

             a small spinning gear appear below the dark gray Apple logo.

     

         2. After the installer loads select your language and click on the Continue

             button. When the menu bar appears select Disk Utility from the Utilities menu.

             After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive

             size.)  Click on the Partition tab in the DU main window.  Set the number of

             partitions to one (1) from the Partitions drop down menu, set the format type to Mac

             OS Extended (Journaled, if supported), then click on the Partition button.

     

         3. When the formatting has completed quit DU and return to the installer.  Proceed

             with the OS X installation and follow the directions included with the installer.

     

         4. When the installation has completed your computer will Restart into the Setup

             Assistant. Be sure you configure your initial admin account with the exact same

             username and password that you used on your old drive. After you finish Setup

             Assistant will complete the installation after which you will be running a fresh

             install of OS X.  You can now begin the update process by opening Software

             Update and installing all recommended updates to bring your installation current.
