Someone suggested getting a new disk drive/SSD, which is a good approach if you don’t mind a relatively hard cutover. But if you have the space and funds for it, it may be simpler to just get another computer and run Linux on it from the beginning, while also keeping your Windows machine running. Then you can gradually migrate your files and activities to Linux as you go. Once you’re not using the Windows machine much any more, just unplug it, don’t throw it out. You can then turn it back on if you need something from it.
