Jason, if your question accurately describes the situation, then you simply installed the Ubuntu One Application for Windows into your windows 7 and you should still be booting into windows. Whether or not you remove the application really should be fairly immaterial. If you do not see it listed in the control panel app for uninstalling programs, you might need to remove it a different way or just ignore it.
If what you installed was actually Ubuntu (the OS), then how you answered questions during the install determined how it was loaded on the machine and whether it lives WITH your Windows or whether you wiped out the Windows system.
In other words, more details would be needed to give you a useful answer.
If the hard drive has been formatted, then Windows 7 is gone. There is no way of getting your old Windows installation back. However, you can install a new one. Usually, that would be done with an installation CD. Since that is not an option, you should head to superuser.com and search for information about installing Windows 7 from an USB drive.
