Once you've opened the Disk Utility, click on the regular partition in the sidebar, not the drive, click on the Erase tab, and erase it.

Use the Disk Utility on the recovery partition to erase the drive, and then reinstall.

You need to do it when started from the recovery partition and not the one with Mac OS X installed.
