Parallels Help moving ISO image I installed http://www.parallels.com/ on my Macbook Pro. Using an ISO image I installed windows on it.

I have an ISO image on my desktop. If I delete it, Parallels says: it's missing, but shall turn on (the operating system).

Is the ISO needed? If so, can I move it to another folder so my desktop stays clean of ISO images? Or do I not need it? (ISO)

I am using OS X 10.9.2 (Mavericks)
The iso is no longer necessary. 
In the bottom of the virtual-machine-window there's a icon that looks like a CD
if you click it you can de-select the .iso (by either choosing disconnect or use phyical drive)
