I have a software problem with the recent upgrade Mac OS X Lion 10.7.4

I have backed up everything and want to erase everything on the hard drive and reinstall … however when I try to start up from the Mac OS X Install DVD by restarting with it in the optical drive, whilst holding the "C" key as the computer starts up … it just starts up as normal from the HD and thus cannot erase it?!!


Can you offer any words of wisdom at all please?
