The recovery disk can't find my OS

Hello, I have a duel boot system (Ubuntu and Windows 7), and my windows 7 boot doesn't work, so I downloaded the Repair CD from this website.

However, when it boots, it doesn't show any operating systems, and says "If your operating system isn't listed, click Load Drivers and then install drivers for your hard disks."

When I click load drivers, it asks me to "Insert the installation media for the device and click OK to select the driver," then it takes me to my system32 folder. Which file should I select in order for the program to find windows 7?
