  • Starting Ubuntu directly from disc

One of the reasons Ubuntu is so popular is that it's so easy to use. Ubuntu is distributed live on either a CD‐ROM or DVD. By live, I mean that Ubuntu can be booted (started) directly from that disc. Forget about spending a long afternoon installing it — you can use it right now.
