As WHS said, you are in overkill. If you image the recovery partition you also will have all the factory bloatware, trial software, and general crap, like the HP tools which do what w7 already has tools for.
The simple answer is image the entire drive, it will be highly compressed and may not be more than 100GB. I have an OS image which is 9.34GB, and the OS is a bit over 20GB.
