Title:
  system installation reboots to grub prompt with zfs

Status in ubiquity package in Ubuntu:
  New

Bug description:
  Focal Fossa Beta ISO installation with Root on ZFS as the only thing
  that is special about this installation.

  Installation seemed to proceed without error, but upon reboot the
  system booted to a blank grub prompt. There were no kernel options to
  choose.

  Looks like my UEFI machine choose to boot ubuntu (sabrent) by default.
  If I interrupt the boot process and choose the non-intuitive sabrent
  option then the machine will boot.

  Since there is no mention in the release notes of having to fix an
  issue such as this, post installation, I'm assuming that this is
  unintended behavior.

  Gigabyte B450 I AORUS PRO WIFI-CF Motherboard with an AMD Ryzen 3
  3200G processor and a Sabrent m.2 storage device.
