As has not been made clear, I've never respun a kernel let alone an ISO!!! .. I know the kernel is okay as it is running on the build machine (having the kernel actually running makes the build less complicated), as I'm basing things on daily builds I will go and pull in the Beta 2 and do a build with that. It will be a few hours, but should be available in a couple of hours. I can then test it in VM to see if the 'cannot mount CD' error is still there.
