Hey guys
I'm trying to do something different from the usual and need your help.
I want to install linuxCNC in a pen drive (as in a live CD, but with the file system in the PEN which is usable)
I want to plug it into my mother's laptop, use it with my machines, then just unplug and it will run the native windows for my father.

How can I do this'?
I only find Live CDs, and I'm afraid of ruining my OS when If I try to install (afraid of installing on the SSD instead of the PEN).
