I want to use Disk Utility to erase my HDD on MacBook Pro. BUT the Erase disk is greyed out. I checked user account and unlocked the padlock for my Admin account. What next please?

MacBook Pro-2.4GhZ- 2GB RAM, Mac OS X (10.6.2), lives with PowerBook 540c, 160 and a Newton 2000

Restart from the Mac OS X 10.6 DVD and use the Disk Utility in the Utilities menu. The active startup disk can't be erased.
