This question already has an answer here:
I've recently updated my ubuntu to 16.10 from 16.04 . I've ISO image of Ubuntu 16.04 (ubuntu-16.04-desktop-amd64.iso) but I donot have iso image of Ubuntu 16.10. How can create it so that I can share Ubuntu 16.10 with my friends and also as a backup in case I need to install it again in the future.
Thank You in advance...!!
