I must point out that copying games is illegal and no advice on how to do so should be give on this site.
More than once I've seen games not install properly on some systems requiring modification of certain files which can only be done once it's copied off (The Sims 2 international version being one of them). The OP wasn't asking to crack the game. Even if he/she installs from the hard drive, it will still require the disc to play. As long as they aren't trying to bypass copy protection features, which there is no evidence of yet, then they're doing nothing wrong. Don't jump the gun there, sparky.
