I want to delete ubuntu 11.10 from dual boot system(windows 7 + ubuntu 11.10). I currently have ubuntu as main OS but I don't want to continue with it further.I don't have CD for win 7 so I am trying other sources. I have downloaded EasyBCD on another system and pasted it on ubuntu. It is .exe file and is not running on ubuntu. I am not aware of any commands regarding installation and further process. :( So,pls suggest what to do next,I would be very thankful. :)
