Bug description:
  The desktop images properly contain both unsigned and signed kernels and boot from the signed one.
  One would expect the installer to keep the signed image on secureboot systems and remove the unsigned one, however it's currently doing the opposite leading to non-bootable systems for those requiring the kernel to be signed.
