And I have machines here that won't boot from an XP disk.
And I'm sure there will be more and more of them as XP gets older and older. Which we all know is a different situation to my surprise that Ubuntu still haven't resolved serious known problems with booting the live CD on a whole bunch of common hardware despite having 18 months to do so.
They work just fine with various Linux distros, though, including (to my own surprise) the latest Ubuntu experimental release (9.04).
What exactly do you mean by that, 9.04 is their latest mainstream release isn't it ?
