I installed a beta release of Windows Vista using Parallels Desktop for Mac 1.0 last year using a Microsoft provided DVD ISO file. So, I thought that installing the production version of Windows Vista using 5 CD ISO files would be a more-or-less similar experience. Unfortunately, I was wrong. Vista's installer apparently got lost in trying to work with the WIM (Windows Image) file format (introduced along with Vista) when used from inside an ISO file (just a guess, btw). So, next up... Installing from real physical CD discs.
