There is a trick if you need to use a DVD/Blu-Ray/etc in a laptop that doesn't have one and if you know in advance. Get a program that makes an image of the disc and then when you need it mount that image and use it as like normal. I forgot what I used to use on my Window's machines but it's something I used to use years ago before rebuying some of my games on steam as I hated having to pop back in a game disc just to play a game.
