Ubuntu 15.10 bootable usb creation

Preparing Bootable USB Flash Drive

We create a bootable USB flash drive with the image we downloaded of Linux Ubuntu 15.10 via Unetbootin available for Linux and Windows
On Linux we enter the sudo password, to have super user privileges, mount the USB volume and select the previously downloaded image
We check that the program is set to write to our flash drive and in case there are files on the device we confirm overwriting
