The first thing that you should do is copy the Outlook stuff off the HD.
The first thing I'd try after that is repairing the startup. That would require a Windows 7 DVD or equivalent. (I've seen location on the Web for download unhacked .iso files of various flavors. It may not be permissible to post the locations here, even though they aren't warez sites. A few seconds of web searching should find MyDigitalLife, though.)
Failing that, you may be able to do what used to be called a repair install, which is installing Windows 7 as an upgrade over itself. Again, that requires a DDV or equivalent. It may not be permitted by an OEM DVD (no upgrade).
