Is it possible to install Freenas from CD?

Hi,
I have Windows Vista. After downloading an ISO file I tried to put that ISO file on a flash drive for netbook of mine so that I thought I could hook up my other external drives on but my netbook has been completely crashed.
I need to know that is it possible to install Freenas from CD because I have already burned it to disc with the help of Active ISO Burner while pulling the flash drive out and hooking it up as externally on vista computer of mine ?
