In the last four years I’ve built three gaming PCs and installed Linux on two and Windows on one.
If you can install Windows on a PC, you can install Linux on a PC. The process of getting the ISO, writing it to a thumb drive, using the BIOS to boot to the thumb drive is the same. The Windows installer is kind of its own environment, but most Linux distros will boot to a “Live environment” that gives you a full desktop you can try out and use before installing, and the installer runs like any other program. Some automatically launch it, some give you an icon to click on the desktop. The installer will ask you the same basic things, though Windows asks you more stuff about their proprietary garbage.
The last time I installed Windows, (Win 10 about a year, year and a half ago) it started up with a fallback video driver and 800x600 resolution, and I had to use Edge to download the GPU driver from AMD’s website. I’ve never had to do that on Linux; AMD drivers are supported directly by the Linux kernel and work out of the box.
I have an unusual speaker system that makes a loud popping sound when the sound chip in the computer turns on and off, so I have to disable a power saving feature by putting a line in a config file. That line I copied and pasted from a forum. It’s entirely because I have this weird old sound system of mine; the vast majority of folks won’t have to do that.
I’ll note that I also choose hardware specifically for Linux compatibility. I use AMD GPUs, I make sure to use Intel wireless chips, I have desktop peripherals that don’t require those goofy dashboard apps to configure. Generally go with as normal as you can.
If you’re coming from Windows, I would suggest trying the Cinnamon or KDE desktops, in the look and feel department they’re probably going to be closer to what you’re used to with robust graphical tools.
Standard disclaimer: Linux is not Windows. You will have some learning and adjusting to do as you get used to a new ecosystem. I don’t think Windows or Linux are free of “troubleshooting.” Stuff goes wrong on Windows too. Thing is, with Linux you can…learn how to fix it?
