Installing Ubuntu 13.10 on an external hard disk drive (HDD) connected to a computer that’s already running another operating system like Windows 7/8 or another Linux distribution is the subject of this article.How to Install Ubuntu 13.10 on an external hard drive
Installing Ubuntu or any other Linux distribution in standalone mode on an HDD is normally a simple, point-and-click operation. To do it on an external HDD connected to a computer running another operating system require a little bit more care, if you don’t want to overwrite the contents of the internal HDDs Master Boot Record (MBR). It’s still a simple process, but you have to watch out!
This tutorial gives those new to Ubuntu and Linux a step-by-step guide on how to complete what should be an easy task. The computer to which the external HDD used for this tutorial is running a self-installed copy of Windows 8. And note that the result of this operation is not the same thing as dual-booting, even though the Ubuntu installer will append an entry for the internal HDDs OS to the boot menu of the external HDD.
