Installing Ubuntu Or Fedora From A Windows Or Linux System With UNetbootin

UNetbootin is a tool that allows you to install various Linux distributions (Ubuntu, Fedora, Mandriva, OpenSuSE, Debian, ArchLinux) from a Windows or a Linux desktop over the internet (i.e., you don’t need to burn the Ubuntu, Fedora, … CDs). Unlike the Ubuntu installation with Wubi, real partitions are created during the installation. In the end, you have a dual-boot system (Linux/Windows or Linux/Linux).
