Try a Popular Version of Linux or BSD
This USB Key contains your choice of one of many versions of Linux or BSD operating systems ISOs. The desktop versions include both live and install capability. The live version allows you to try it out without overwriting your current Windows operating system software. The live version contains all the drivers needed to connect to your local network and attached devices such as your printer, video monitor, and etc. If you have not tried Linux yet, you're most likely going to like it. It is not as much of a headache as Windows. Everything just works and it's a graphical interface that is point and click.
Install Linux or BSD Either Alone or With Another Operating System
Once you have tried it and like it enough to decide to install it one your hard drive, you can choose to completely over-write your current OS or install along side Windows so that you have both available to you in a dual boot system.
Note: server versions of these operating systems usually do not include a graphical user interface (GUI) such as Gnome. The server versions are typically used to perform background operations such as network file back-ups, hosting a web server, network name resolution (DNS), IP address assignment (DHCP), and media streaming (DLNA). Typically server operating systems are managed from the command line interface (CLI), a remote web application such as Webmin, or a terminal interface. We recommend installing these point and click systems for network training or experienced data center technicians and engineers.
