installing hardy from live

[michael weaver]

how do you install hardy with orca after running the live cd?
i ask because at the moment i have got a hardy cd which i burned 
before experienceing problems with my laptop and i have a copy of 
lucid beta which will not allow me to login after going through 
the setup because it says "welcome to orca" just after asking me 
if i wish to logout after running through the settup.
