If the games have copy protection, you may be out of luck (unless you also have a No-CD or similar... but thats up to you, and I wouldn't recommend it).
If the games just come on cd, simply create a new folder somewhere and then two sub folders,
Disk 1 and
Disk 2, copy everything from the cd to the relevant folder and use your favourite burning tool such as CDBurnerXP or ImgBurn (Both available on Ninite).
Now, when you put the disk in, simply go to the relevant folder and install. If the game does have copy protection, you may have luck with Jared's answer (I would use Clone Drive over Daemon Tools), simply because that trys to emulate the copy protection - obviously though you have to install that on each machine you want to use, but you can always keep the setup file on the root of the disk.
