Stopping VM and unmounting ISO

[Dark_Gypsy]

Ok, so I have to be doing something incredible wrong here. I am installing ubuntu server as a VM. I mount the ISO , allocate resources, start it up, do the install, and all goes well. I get to the end and it want's me to reboot to finish the installation. No problem... except there is. I click "stop" , and the VM does nothing... If I can't shut it down I can't eject the ISO. Ok, so I hit force stop... it shuts down, i have the icon to eject the ISO, and I hit it, and it gives an error and will not unmount. So basically I have a fully installed VM that I can't access because when I reboot it goes right back to the install because the ISO is still mounted. Tell me I am a clown, and I am doing something wrong... PLEASE!!!
