Trying Linux? 
If you are interested to try a Linux OS on your own Windows C, we recommend to install the current distribution of Ubuntu. You can install Ubuntu onto a computer alongside a copy of Windows. You will be able to select whether to start Ubuntu or Windows each time your computer starts up or you can try to run Ubuntu on a CD or even on a memory stick alongside your current system.
Feel free to ask our instructors for guidance!
