My apologies *up front* if this is a dumb question, but I am new to the Mac and even newer to the concept of installing Windows on an Apple machine. I want to install Parallels or Fusion on my 1.66 GHz Core Duo (2GB memory) Mac Mini. I only have about 25GB of disk space available on the machine, and I don't want to use much of it. I also have a 50GB external hard drive connected to the mini. Is it possible to install Parallels or Fusion and then Windows on this mini and use the external hard drive for the Windows partition?
