Hi, I know many people have probably answered this question already, but, I am a new Linux user transfered from Windows 10 preview into Linux Mint 17 Cinnamon. I came into Linux knowing a few things about it, but I am confused about installing Call of Duty 4 Modern Warfare. I tried to install it along with Mafia 2, and keep running into the same problem. It asks me where the mounted drive is. Please help? My problems are 1.) I don't know where the CD DD is, and 2.) Do I still need a physical copy even if I am installing from POL? Thank you for any and all help.
