i believe he's using like a Win98 disk(sorta of) to boot from and then start the install..... as for wasting CDs, use VirtualPC or VMWare workstation. Then it only takes the time it takes to recreate the ISO. i wonder why command.com doesn't load, UNLESS you either don't have your disk set in the path, or your not using a full path. Some forms of DOS are quite picky and just to be safe, it's always good to include drive letters
