[Bug 1768621] Re: Installation of Ubuntu 18.04 Desktop installation crashes when unable to write Grub

[Phillip Susi]

Your disk is currently partitioned to boot in bios mode, but you booted
the installer in EFI mode. You either need to boot the installer in bios
mode, 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:
  Installation of Ubuntu 18.04 Desktop installation crashes when unable
  to write Grub

Status in grub-installer package in Ubuntu:
  Invalid

Bug description:
  Attempting to install Ubuntu Desktop 18.04 to a second HDD (primary is
  reserved for Windows 7 Pro, and I don't want to touch it with a
  partition manager). Reserved 220GB of hard disk space for the root
  partition, and another 30GB for swap. The installer was able to get
  nearly all the way through the installation process (according to the
  progress bar, probably 80%) when suddenly it crashed and notified me
  that writing (I assume) grub to the MBR had failed and that the
  installer was not going to continue.

  No reboot has been attempted yet, but my plan is to shut down,
  disconnect unused drives (Win7, external HDD), and attempt to boot out
  of the 250GB drive as is. If this fails, I'll attempt another install
  with extraneous drives still disconnected and allowing the installer
  to automatically determine the ideal partition setup.
