I want to factory reset my macbook pro but my computer doesn't give me the recovery option, it gives me Macintosh HD only.

Hello sallay Amir,

Thanks for participating in the Apple Support Communities.

It sounds like you would like to erase your MacBook Pro and install a new copy of OS X, but the Mac does not boot to OS X Recovery when you hold the Command + R keys during startup.

If your Mac came with OS X Snow Leopard (10.6) or earlier, I recommend referring to the steps in this article:

Mac OS X v10.6 Snow Leopard: How to Erase and Install - Apple Support

For a newer Mac (OS X Lion, Mountain Lion, Mavericks or Yosemite), try reinstalling OS X by using Internet Recovery, as described in the "OS X Internet Recovery" section on this page:

OS X: About OS X Recovery - Apple Support

All the best,

Jeremy
