The MacBook Pro has been produced for 10 years. It’s impossible to give you an knowledgable answer without knowing which one you have: http://www.everymac.com/systems/apple/ma…
If you have compatible OS X installer disk for your computer, power on the Macbook, hold down ALT(option) key until you see the available partitions, then insert the disk and choose it. You can do this with a Flash Drive as well as DVD. In this case first you have to download your OS’s installer from the App Store.
