Why am I getting an error message in recovery mode unknown error?

[iMore Question]

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.

Re: In the recovery mode i have an "unknown" error...

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?
