I did a bit of googling and this site came up Nocd patch? but I'm not sure how real it is... there is a limit to how far I go into such sites
If it is a scam or dead link then maybe you can change the registry keys to look in the folder where you installed the game instead of the CDrom drive? Or even check for config files that might be altered to fix this.
Or make an iso as suggested
