Newbie Question: How to Release CD/DVD

[mgeeca]

I've installed Ubuntu in a VirtualBox VM. I can run Ubuntu as long as I leave the ISO on a disk in the DVD drive. How can I switch to the ISO on the hard drive?

Ubuntu setup CDs can either be run as a "live CD" - requiring that you insert the ISO every time, or you can install them to the VM hard drive. If you install them to the hard drive then you don't need the ISO to be present - simply unmount it from the VM using the VM settings storage section, or the Devices menu of a running VM. The same menus can be used to mount a different ISO, or a copy of the same ISO located on a different drive.
