How do you boot from the internal optical drive in Heads?
When Heads starts, it doesn’t mount the optical disc (and hence doesn’t see its OS as a boot option). I don’t seem to be able to find any option where I can change the boot disk to any type of media except USB drives.
/dev/sr0 shows up and can be mounted from the recovery shell. However, the command to start a kernel is fairly complicated (Heads Recovery Shell | Heads - Wiki) and depends on finding the right boot directory on the disc.
Is there a way to get back into the Heads boot options after first going to the recovery shell? That would be the easiest probably if I could mount it first and then hopefully it would show up.
