Look in the ubuntu's forum (if they got one. Never been there) and look for 'Poor Man Installation'. that's how is called what you want to do with the ubuntu.iso or google it

Knoppix's Poor Man Installation

When I ordered Ubuntu from their website, they sent me two CDs: 1. a live CD. 2. an install CD.

Do you have the right CD?
