Now I did search the forum, but I couldn't find exactly what I'm looking for. I have the .iso files for the three Doom 3 CDs, and am trying to install it. I mounted disc 1 on a VD using Alcohol 120, and everything was installing fine until it asked me to insert disc 2. I unmounted disc 1 and mounted disc 2 in it's place, but Doom 3 wouldn't recognize it. I clicked OK at the installer, but it just kept giving me the "insert disc 2" message. So I tried burning them to CDs instead, but after burning disc 1 I tried playing it and my computer doesn't recognize it. Says "Windows cannot recognize the media type or it is not formatted." Or something of that sort. What am I doing wrong?
