Welcome to Apple Support Communities

From what you say, you may have formatted the wrong partition during setup, so you may have lost OS X.

To check whether you have any operating system installed on your Mac, first turn it off. Then, turn it on and hold the Option (Alt) key until your Mac shows all bootable volumes. Tell me the names of the options you see.
