I recently bought a Windows DVD to put it on the new PC I'm building for my mom. That PC has troubles with the DVD drive itself (stupid motherboard doesn't have IDE..), so I figured I'd set up a bootable USB to install Windows before the adapter arrives. Problem is, the installation DVD isn't playing on my drive (I tried another DVD with a movie on it before, so I don't think its my drive). I brought it to a PC shop and for them it worked fine, even though its quite scratched on the back (I guess the person selling those DVDs doesn't know how to ship them properly) I didn't wanna pay 20 bucks for them copying the DVD, even though I'll probably end up having to do that. Any ideas what the problem is, or what I can do? I'm not sure if the DVD will work in my moms drive either..
