noob with no cd question

[spamel]

Indeed, I am British!!

Like I say, I'm not too clued up with these gizmos, I run anti virus and firewall, etc. but I won't be on the internet with it, and I will NOT be putting other discs from unreliable sources onto my laptop!! You can't trust some people these days!!! Hopefully I won't need to reinstall windows at all.

Coming back to the no cd patch thingy, I keep getting asked to put the cd in, but I made a backup disc, so I'll go with that. I want to do this with all of my games as I don't want them getting eaten by camels and what not!! Is this strictly legal as long as I own the original game?
