[Bug 1761689] Re: Grub2 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:
  Grub2 failed to install

Status in grub-installer package in Ubuntu:
  Invalid

Bug description:
  I was upgrading from 16.04 to 18.04. The main reason for upgrade is
  constant problems with WI-FI in 16.04.

  I have a UEFI system, hence, in my view, GRUB is not required.
  However, Ubuntu installs GRUB by default. I had the GRUB installed
  from 16.04. I had tried removing the GRUB using CMD commands before
  trying to install 18.04. However, when I rebooted the system, GRUB
  greeted me to 16.04.

  I started 18.04 installation as an upgrade to 16.04. The installer
  failed to install GRUB.
