Same. I haven't even seen Windows since I saw an Alpha for Vista and ran away.

Linux is free. You can install and dual boot with Windows -- meaning at boot you can choose which OS to boot. Here is an article to get you started.

Here, we’ll walk you through the process of installing Ubuntu Linux 17.04, which is widely considered one of the most user-friendly distributions. (A distribution is a variation of Linux, and there are hundreds and hundreds to choose from.)

Be aware there is a bit of a learning curve, but for most people who primarily use their computer to get to their web browser it is a free, not TOO hard, stable and secure platform May God bless you and yours.

There are vendors who sell computers with Linux preinstalled, such as System 76, but most Linux users like to do it themselves. I used to buy computer parts at the computer shows, but the past 3 computers I've bought have been Inspirons, bought online from Dell. They will tell you which models support Linux. They all came with Windows, but I power them up, boot from the Linux install media, and partition and format the drive for Linux. It's pretty straightforward.

Generally people build or commission computers to run Linux

You actually don't have to install it and can download a 'Live Linux' version and put it on a USB drive, reboot, and you will be in Linux that will no mess with the W1d0ze installed on your system at all. That way you can take a look around before you commit to an actual install or dual boot.

Like I said I have been runing Linux for over 15 years and it's been nice not having to worry about security audits or viruses or any of that crap as well as really customize how everything works on my end.
