UNetbootin is a free application to start the computer using the Linux operating system by an external device.
UNetbootin facilitates the creation of USB drives to boot the computer operating systems such as Ubuntu, Fedora, Debian, Gentoo, openSUSE, Dreamlinux, PCLinuxOS, MEPIS, NetBSD, Free BSD and any other Linux distribution without having to burn a CD or DVD.
With UNetbootin you can work on a computer with Linux, Windows or Macintosh because it is a multi-platform.
UNetbootin allows you to run Linux distributions by automatically downloading their ISO files. Linux distributions are collections of programs and files, open source, they are organized and prepared for installation. Are obtained over the Internet via FTP or by direct download from a website. They can also be stored on an external device such as a CD, DVD or external drive.
UNetbootin does not interfere with the operating system installed on the computer where you work so you do not have to worry about the loss of files or data, and that this free application leaves intact the original installation. What makes UNetbootin is to create a new space for Linux, thus having two operating systems on one computer.
If you want to experiment with Linux distributions UNetbootin is an excellent software to get you started with confidence.
