Ubuntu is one flavor of Linux
It is open source code so there are many flavors.
Anywhoo its all free, and there is no need to install it on your machine to try it.
It will run live off of a CD.
Like it? Install it dont like it? No worries.
Great recovery tool if you regular OS crapped the bed.
Maybe I’ll get out my old slow Dell and fiddle around with it.
My MacBook and FiOS 78mps is wicked fast so there’s not a lot of incentive there.
