[Bug 1614252] Re: GRUB2 installation failed during xubuntu installation on laptop with UEFI SecureBoot on, clean disk

[Phillip Susi]

Your disk is currently partitioned to boot in bios mode, but you booted
the 16.04 installer in EFI mode. A warning message prompted you that
this could be a problem and recommended performing a bios mode install
instead, but you chose not to. You either need to perform the bios mode
install, or partition the disk using GPT and set up an EFI system
partition to install in EFI mode. This will be done for you if you
choose the "use entire disk" guided install option.

Title:
  GRUB2 installation failed during xubuntu installation on laptop with
  UEFI SecureBoot on, clean disk

Status in grub-installer package in Ubuntu:
  Invalid

Bug description:
  PC: Lenovo G50-45
  UEFI SecureBoot was left on
  Wiped disk before installation
  Created a 4GB ext2 /boot and an 8GB ext4 /root partitions, the rest inside an LVM volume group on a LUKS container. No EFI partition (didn't know I needed one as this is the first time I install Ubuntu on a non-BIOS machine).
