Help! I'm stuck with Windows :-(
Microsoft Windows is shiny and fun, but unfortunately not well-suited to much beyond browsing the internet. If you don't have access to anything else, however, we recommend that you set up Ubuntu Linux on your computer using VirtualBox. For instructions about how to do this, see this tutorial. Be sure to give Ubuntu as much memory (RAM) as you can; 1/4 to 1/2 of your total system memory should be safe.
Start early!
Please start this process as early as possible, so that we can help you with any problems that may arise!
