Then, when time for an upgrade, install a new Mythbuntu to a different partition***, and boot into that system. If you're not happy, boot back into the old partition to record that important show during prime time and to relax and watch some TV, then boot back to the new partition to work on it some more when you get some free time. This gives you the same ability to easily switch back and forth between the two installs that you get with a VM. The only thing you don't get is the ability to run both at the same time.<br>
