This question already has an answer here:
I have nothing against Ubuntu. Completely satisfied with its performance. But after some while now, I don't have much hard disk space for my own files. So I'm planning to keep Windows 7 and uninstall Ubuntu.
Currently I get dual boot options when I turn on my PC. I got to know that uninstalling Ubuntu would result in some repair work to be done for Windows 7. Please fill me in with details on this, and on how to uninstall Ubuntu, because I have an uninstall file in Windows 7 in the location where I have installed Ubuntu.
