I just got my OWC On-The-Go-Pro external enclosure today and put a 320GB hard drive in there to run Windows off of it exclusively. How would I go about doing this? I am planning to get Parallels and a copy of Windows 7. What I want to do is run Windows 7 off of this drive and would like to know what format to put the drive in before I install Parallels. Should I also buy Parallels now or is there an imminent refresh coming up? Thanks!
