Fully migrating from Windows to Linux is not for everyone, you may not want that unless you know to user a computer in a good or expert way but you can use them both on your PC: you can run Windows on a virtual machine in Linux (I can say it for sure, i don't know if you can Linux on a virtual machine on Windows because I havet not using Windows for more than a decade) or you can choose your operating system when you start your computer.
Anyway, try to be informed. You may not want to switch your operating system right now but you should know you have an option. You can even run at least a few application made for Windows on Linux using Wine.
