What is the best way to make an ISO file out of a DVD?
ImgBurn is a nice, free tool for creating disc images as well as burning them.
Be forwarned that the installer off the imgburn website contains the opencandy adware - so you may want to look for the alternate, adware-free mirrors
Most people will already have 7zip installed. I tried this and it works.
- Run 7-Zip File Manager
- Open top level folder (by clicking the upfolder button several times, or clear the address bar and hit enter)
- Open "\\." item
- Select DVD drive item, press F5 (Copy), and select the folder to write ISO image.
Like @Joakim points out in the comments: you can also download the iso again. But if you want to save on bandwidth:
LC ISO Creator is very small, lightweight, free and portable!
