A lot of people get started in a computer career using only Windows workstations and servers. But in short order they will find that they need to have at least some knowledge and experience with Linux. Linux is a huge subject area, and often people try to dive right into the deep end first thing. Then they get all frustrated and decide it is too hard to learn. In doing so they also turn their back on a lot of higher paying IT positions. But it is not really all that hard to learn the basics of Linux. My recommendation is to always start with using it as a basic workstation. You can do this by either setting up your computer for dual boot, or by installing Linux into a virtual machine on your desktop using something like VirtualBox, HyperV, or VMWare. I am a huge fan of using virtual computers for learning. It takes a lot of that fear factor away. And if you mess up the computer it is so easy to start over. Or if you know you are trying something risky you can set a snapshot that you can easily roll back to also.
I recently launched an Intro to Linux course on Udemy. I have created a coupon to get the class for $10 for the first 100 people that click on this link between now and November 30th. After that you can go to https://www.udemy.com/introduction-to-linux/ to sign up. To entice you a bit here is the lecture for installing Linux.
I am truly a geeks geek. I have worked in computers for over three decades. I have worked on mainframes, Unix systems, Linux before almost anyone knew what it was, and many other systems. I love computers, and love making them do things people think is impossible.
