I am looking for a way to prepare an image of an Ubuntu machine which would be bootable and installable in the easiest way possible.
I'm actually preparing an Ubuntu machine for someone living far, and not computer savvy. If he ever has troubles with his installation, he could just put a USB drive in, boot the machine and everything would be resetted for him.
I know there are many methods of creating/loading an image of a drive, but the ones I've found so far have complicated menus with several options to choose from, etc. Ideally, perhaps only asking a Yes/No question such as "Would you like to reinstall?" would be great.
Does such a tool exist?
Thank you in advance!
