How do I uninstall Ubuntu from within Windows 7?

[subhapk]

I installed ubundu on my system, since this dvd has put in genuin windows it did not ask for partition instead it asked whether to put in entire disk ]or in the last disk space. I hope that I selected the entire disk. So now only ubundu is seen in my system will windows is gone how do I get windows

Use the Windows installation media to install it. Do you just want Windows or are you trying to do a dual boot?
