[Bug 1687811] Re: 16.04 Mate - GRUB-EFI-amd64-signed package failed to install

[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:
  16.04 Mate - GRUB-EFI-amd64-signed package failed to install

Status in grub-installer package in Ubuntu:
  Invalid

Bug description:
  Install of 16.04 Mate desktop (MD5Sum verified as correct) install on top of existing openSuSE 42.2 install. Previous install had BTRFS for / partition, XFS for dedicated /home partition. Used the "Something else" partition option and choose to increase the size of SWAP for VMWare, deleted /home and added it back with less space using EXT4, with FORMAT checked; newly freed space was given to SWAP. Changed / partition to EXT4 with FORMAT checked.
  Installer crashes with "GRUB-EFI-amd64-signed package failed to install into /target/"
