partitioning - How to uninstall Ubuntu from one drive and install in another drive?

I've recently installed Ubuntu 13.04. On the installation process I've select "Install Ubuntu Alongside Windows 7" or the option similar of that. So I didn't know in which drive Ubuntu is installed (Windows 7 is in drive C). I didn't find out any option on Control Panel (in Windows 7) to remove Ubuntu. Can anyone tell me how to remove Ubuntu so that I can install it in my desire drive?

Thanks
