You can get a great program called Alcohol 52%--what it does is makes "virtual drives" on your laptop so you can turn nearly any game into a "game with no disk".
http://www.alcohol-software.com/ You put in your original cd, and it copies the cd to your hard disk. Then you load that disk image you just made into a "Virtual cd drive" and the computer thinks it is looking at a real cd drive with a cd in it. I used this all the time on my laptop with no internal cd-drive (I used a USB one to load the games). I even use it on my desktop sometimes to cut down on noise and speed up loading. It's also handy with games with multiple discs that support multiple cd-rom drives as you can put all the cds in, say, 6 different virtual drives and never have to swap them! They also have one called Alcohol 120% adds the feature from 52% of letting you burn these images you make on cd-rs, in case you want to make backups of your games if you fear for them getting scratched up or broken or whatever.
There is also a free program that does similar, but doesn't have as many features and is a bit more complicated:
