Is it possible to create Windows installation media that requires more than one disk (DVD or Dual Layer), and have it install properly? I understand disk spanning (somewhat), but don't want to waste time or disks creating the media if the OS will not install and work properly from the spanned discs. The size of the media I would like to create is about 18-21 gigs in size. The media would include the installation Windows 7 Professional media for my Dell PC, all current KB updates and patches, current drivers for my system, and several programs that I currently have installed on the PC I'm currently using (AV, AM, Open Office, and more). I'm currently working to create an ISO for the project and would just like to know if it's going to work once it's done, or if the disk spanning will mess things up.
