I installed a Windows 8 from an ISO to VirtualBox running on Ubuntu. Everything works fine, but I deleted the initial ISO that it was installed from. Now I get the error in the title (it says it is a "Warning.") Windows 8 still seems to work fine and I can shut it down, pause the virtual machine, etc. with no problems. It seems like this is just a warning because the ISO was deleted.
- Is this just a warning?
- Why does VirtualBox care about the ISO post installation?
- Is there anything I should do to prevent the warning from popping up?
