What options do I have if I'd like to install manjaro on my usb-stick without having to reboot my maschine.In that manner I can do my work while Linux installes. And when the installation is finished I'd boot that OS on the Stick with VirtualBox as I found a howto here.  I need to have that OS on a stick, so that I can use to boot that OS on other machines to fix stuff.
