I am playing around with Virtual Box and installed an Ubuntu 12.04 ISO on a my first VM. Now I want to "wipe" that VM clean and undo all the software I had installed on it. My co-worker said the easiest thing to do is to just re-install Ubuntu and overwrite everything.
What's the easiest way to do this with VBox? Should I just delete the whole VM and recreate it from scratch? It would be nice if I can just tell VBox "hey, take this VM, erase everything on it, and then replace it with this ISO" instead of having to delete the entire VM and create a new one. Is this possible? If so, how? If not, what's my best remedy here? Thanks in advance!
