Primarily Unetbootin allows you to install a version of Linux via a network connection (without any CD), however I think it’s greatest value comes from the option to install “Visparted”. Visparted allows you to resize and move most types of partition (including NTFS) and is easy to use.

Purchase a new PC or motherboard soon, and the chances are good that it will come with two built-in network interfaces -- either two Ethernet jacks or one Ethernet and one Wi-Fi. Tossing in a second adapter is an inexpensive way for the manufacturer to add another bullet point to the product description -- but what exactly are you supposed to do with it? If you are running Linux, you have several alternatives.
