If your computer boots normally to your desktop then you do not have a recovery partition. If your computer boots into a four-option menu then you have a functional recovery partition that can install the OS. To make sure you have a functional recovery partition, restart your computer and immediately hold down the Command + R keys until the Apple logo appears.
