Q: Mac OS X Lion v10.7.4: How to erase and install

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?

MacBook Pro, iOS 5.0.1
