Battlefield 2 Newb help

[so2315]

I bought the BF2 PCCD version. I want to get the game to run without using the original disc as I have 3 kids who are rough with discs and damage them. I used to always find no cd cracks for my games but see this one has image files. I only have Nero to burn, and was wondering how to make a copy of my original disc so I can put it away from the kids?
I am asking a legit question on backing up my own copy. Can anybody give me step by step instructions on backing this game up? I know nothing about virtual drives also.
