Before reinstalling OS X, choose disk utility from the OS X utilities table. Navigate to your hard drive or volume your system is on, Macintosh HD if not changed. Select the erase tab, choose Mac OS extended journaled as the format, and click the erase button. If you want to set options for a secure erase, click security options and use the slider to determine the level of security for your erase. Keep in mind that this erases all your data, so you should make a backup of all important files. Once erased and reformatted, quit disk utility and choose reinstall OS X from the OS X utilities table.
