Windows 8 has a feature called Windows 8 To Go, where you can install the OS to a flash drive and boot to it, without ever having to install it on your hard drive. Is there any way to do this or, something similar, with Ubuntu, or some other Linux distro? I have an Ubuntu installation disk, and when I boot to it, there is the option to either install it or to try it out without installing. Any setting I change or anything I install, of course, is not saved on a reboot, because it's not an actual installation. But is there some way to do this, so I have a portable OS? Thanks!
