Welcome to the forums :emotion-21:     You don't have to use a specific Dell ISO image.  Just download/install the latest original Ubuntu image off the Ubuntu website :emotion-5: Remember though... Dell won't provide you with support, if/when you install Ubuntu... unless you dual-boot it with Vista. They only provide support if you're still using the OS which was pre-installed on the system when you bought it :emotion-55:
