"A graphic installer makes it easier for myself as well as you
the reader to follow my instructions. I am sure you would dread a
laundry list of commands you would have to type in order to install
Linux to your hard drive.
"Ubuntu is a highly popular Linux distribution. It often ranks
#1 on distowatch.com (a distribution tracking website). I see no
reason to use an unpopular distro of Linux as you may need help in
using it further down the road. Using Ubuntu ensures you have a
community to fall back on for your support needs.
"Ubuntu has many official variants. Ubuntu uses the GNOME
desktop environment by default but you may prefer KDE. In that case
you could use Ubuntu's KDE version called Kubuntu."
