After using Windows Ubuntu Installer from within Windows, I am prompted to restart, so I follow the directions. When I try to start Ubuntu after restarting, the desktop background appears, but then a loading bar with this title appears.

Verifying the installation configuration...

While this is loading, an error window pops up that says

No root file system is defined

Please correct this from the partitioning menu

There is only an 'Ok' button available to click, and if I click that the same error window appears. I do not know how to get to the "partitioning menu" from this state, so the only option I have is to shut down my computer.

What can I do so that Ubuntu finds a "root file system"? Can I diagnose this problem via Windows? Does anyone have any insight?

FYI - I am using a new ultrabook with 6GB RAM, Intel i7 3rd gen processor, and no CD/DVD drive.

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version.
