[Bug 1667990] Re: XUbuntu installer crashed due to uefi error

[Phillip Susi]

Your disk is currently partitioned to boot in bios mode, but you booted
the 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:
  XUbuntu installer crashed due to uefi error

Status in grub-installer package in Ubuntu:
  Invalid

Bug description:
  Was installing XUbuntu. I chose to install additional drivers. The
  installer informed me that secure boot would have to be deactivated
  for these to be installed, but the installer would help me do that if
  I just created a password that I would be asked about later.

  Then after clicking ok, another window told me that the installer had
  started in UEFI mode, and I might not be able to boot any existing
  OSes after the install, which I didn't mind because I was installing
  on a harddrive with no pre-existing partitions, and therefore no
  existing OSes, so I chose to continue installing in UEFI mode.

  This seemed like a reasonable choice to me, not exactly knowing that
  secure boot and UEFI are, let alone telling the two apart. Actually,
  even being presented with these rather cryptic messages didn't seem
  like a very user friendly experience to me.
