Debian, World’s Easiest GNU/Linux Distro You Can Install
It may have been true years ago that Debian GNU/Linux took some time and trouble to install. That’s not true today. A basic installation is pretty trivial.
“Assume the default” works in most cases where user-input is required. There is an even better option for newbies. If the newbie doesn’t mind the whole hard drive being taken over by Debian GNU/Linux (you don’t want to preserver the current OS/data) then there is a trivial method, FAI (Fully Automated installation). FAI is meant to be used by system administrators who want a scripted means of installing on random PCs. By providing reasonable defaults, such a system can be put on a CD.
