Create Image File to use with Daemon Tools

I bought a Notebook with no cd/dvd drive. I have software disks (legal) I want to load to the Notebook. I was told I could create an image and read this with Daemon Tools cutting out the need to buy an external USB CD/DVD drive. I have Nero 8 and Daemon Tools. Can anyone tell me how to create the image of the software (on disk) so I can copy it to a USB stick and read with Daemon Tools on the new notebook please?

Got it sorted. Used Nero Burning ROM, Copy and removed the tick to delete the work file when cloing Nero. I then copied the image file to a USB stick and read this with Daemon Tools on the Notebook. Worked a treat.
