    Default In the recovery mode i have an "unknown" error...

    I try to reinstall Yosemite OS X using "Reinstall OS X" in OS X Utilities. When i selct and press Continue i get a new window that says

    " OS X Yosemite
    To set up the installation of OS X 10.10, click Continue.
    when i click, a dialog window pops up with a message

    to download and restore OS X, your computer eligibility will be verified with Apple.

    with "Cancel" and Continue buttons.

    When i click continue i get the following message

    An error occurred while preparing the installation. Try running the application again

    with an OK button. When the button is pressed, it returns back to the OS X Utilities.

    My wireless seems connected.

    Have you verified that you indeed have a good internet connection? Can you get to your desktop screen to install Yosemite via the App Store? If you can't get to your desktop screen, have you made a bootable disk to be able to install OS X Yosemite from scratch?
