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!
Thanks @Deltik (+1) - I presume I accomplish this in Settings >> Storage? I see an "Attributes" section with a CD icon that allows me to choose an ISO? Do I just choose the same ISO as before (would doing so cause VBox to overwrite my old VM with the new ISO)? – pnongrata – 2012-07-29T20:42:14.603
@zharvey You replace the
.vdi
file with a new one. (Sorry for the late clarification, but I'm on a different computer right now, so I just downloaded VirtualBox to get screenshots.) – Deltik – 2012-07-29T20:45:31.820Thanks again - I removed my existing attachment and added a new one (pointing to my Ubuntu ISO). I restarted the VM and got the following error:
FATAL: Could not read from the boot medium. System halted.
Where am I going wrong here? Thanks again! – pnongrata – 2012-07-29T20:54:28.383Create a new hard disk. Don't point it to the ISO file. Then start up the virtual machine. You'll still get the fatal error, but go to

, choose your ISO file, then reset the virtual machine. (Screenshot)
