I'm hoping someone can give me some advice about installing Windows XP Professional on a Mac Book Pro. I'm getting ready to make the switch from XP to Mac. I have two applications that I absolutely need on the Mac that are Windows only. (Both help me control my diabetes.) Since I already own Windows XP Professional and have the product key, can I reinstall it on the Mac Book Pro (after installing Parallel or Fusion of course)? Has anyone done this? I cannot find the cd, unfortunately, but as I noted, I do have the product key. Thanks!
