Just ditch windows. Well you can leave it there if you want to. When installing Linux the installer will ask you if you want to leave windows alone. It will pushing windows to the side, create some partitions and you will have 2 OS’s in your system, its called dual-booting. There are tons of videos in YouTube how to install Linux operating system. I started using Linux out of college, got tired of paying for the high prices for the windows CDs I’ll never look back. Today we have Android smartphones all over the world ( Android is Linux).
