If you have never tried Linux, try it yourself and get familiar with using it. For a more detailed explanation of what Linux is, go to “What is Linux?” at opensource.com: https://opensource.com/resources/what-is-linux
Luckily, most versions of Linux can be obtained free of charge and they tend to run well on older computer hardware. You do not need to get a brand new computer to use it.
You will need a computer to experiment with. While it does not have to be a recent machine, it should have a 64 bit processor with a minimum of two cores. This would include pretty much every desktop or laptop made in the last 12 years, and older ones are available very cheaply. You will also need at least 4GB of RAM, although more is almost always better.
Next, go get the version of Linux you wish to try. The place I recommend people start is with Ubuntu, the most popular distribution (or distro) of Linux in the world. On your regular computer, go to https://www.ubuntu.com/download/desktop and download Ubuntu file.
Then, assuming you regularly use a Windows computer, format a USB flash drive to install Ubuntu. You might want to find a friend to help you with this step. Someone at your local public library or maker space may be able to assist, too.

Once you have your flash drive formatted for installation, put it in the computer on which you will be installing Linux. You may need to change the boot order. This will allow the computer to boot from the disc or flash drive, rather than the computer’s hard drive, as it normally would. This is done by using one of the “F” keys at the top of your keyboard when you first turn on your computer. Which “F” key you use will differ, depending on the manufacturer of the computer. If you are unsure, do an online search on “changing boot order” on the make and model of your computer.
Once you have successfully booted from the disc or flash drive, follow the onscreen instructions to install. Included with this guide are supplementary installation sheets with more detailed instructions.
Once you have Ubuntu (or some other Linux distro) installed on your computer, have some fun with it. Experiment. Use the Firefox browser (it comes with Ubuntu) to go online to look for ideas of what to do with the computer. Go into the Software Center to find other programs to install and try. You will find that the myth of there being no programs for Linux will quickly evaporate, as there are tens of thousands of Linux programs available in just about every category you can imagine.
Go online to learn more about using Linux. A few websites to look at for ideas would include:
If you are looking for current Linux news, a great place to start is Linux Today: Linux Today.
Over the last several years, several YouTube channels devoted to Linux and Open Source software have come onto the scene, and they can be a great place to learn new things. Here are some of my favorites:
The aim at this point is not to become a “Linux expert”. It is to simply familiarize yourself with the software, explore, experiment, and have fun. And remember, if you really mess something up with your Linux computer, you still have the installation flash drive. You can always start over.
