But you don’t have to remove windows. You can install linux in another partition and have an option to choose which system you want to boot. If I remember well, the ubuntu installer has an option t do that automatically ( I will check for you later) . You can also install linux to an external usb media for testing and insert it every time you want to give it a try (usually, pressing f12 or other vendor-specific combination at boot time allows you to choose boot media)
