@Akshay: 2 guys have already suggested it to you. Your dvd is useless now cos you have activated your game on steam. Infact, you can delete your game later on & redownload all the COD MW2 files through steam & steam will never ask you to insert your disk ever again.
Lastly, only the single player campaign can be played offline but even then also you will have to login through steam & select "Go Offline" option. For multiplayer, you have to go online otherwise no multiplayer for you.
