There is a flashing folder with a question mark on the folder and the computer will not start up.  What does this mean?

    That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.

    With 10.4, 10.5 or 10.6 put your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option Key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.

    Or if you are running 10.7 Lion or 10.8 Mountain Lion, boot from the recovery partition (Command +R on boot) and use Disk Utility to repair your OS 10.7 or 10.8 partition.

    When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk
    Utility and click it. When it comes up is your Hard Drive in the list on the left?

    If it is, then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive.

    If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

    I have a very interesting problem.

    My hard disk is functioning, but working slow. That's why I want to upgrade to a SSD.


    The SSD is working very well on a Macbook Pro 13" early 2011 from a friend and one Macbook Pro 15" 2014, but not mine.


    When I replace the harddisk with the SSD I get the  Flashing folder with Question mark.


    I replaced the harddisk cable, but with no result.


    I also did a PRAM reset.

    I am desperate for a solution.
