Try starting up holding COMMAND R hold till you see the spinng gear and allow it to boot, click disk utility then continue. On the disk utility screen that pops up select(highlight) your volume (default name Macintosh HD) from the left column, click the Erase tab, set the format to Mac OS Extended (Journaled)
Set the name (you can use Macintosh HD or what ever you like)
Click erase, quit disk utilties and then click Reinstall Mac OS X.
