Bootcamp icon is lost on Mac Desktop

I used to reach al my dcument in Windows 7 by bootcamps. Unfortunatly, today the bootcamp ıcon has lost on mac desktop and can not reach my documents in windows 7. However, when ı use windows 7 can reach all my documents in mac.

Do you think ı deleted the ıcon or it is deleted because ı made wrong updates or donwloads?
