[Bug 1759099] Re: GRUB2 version 2.02~beta3-4ubuntu7.2 causes unbootable system

[Mathieu Trudel-Lapierre]

Should be fixed in 2.02~beta3-4ubuntu7.3; the flashing should be solved
which should be avoiding the crashes (which are likely due to the
graphics card really not liking the flickering).

Can you please confirm whether updating to the new pacakge fixes the
problem?

Can you reach a good menu by hitting the ESC key quickly at the start?

Title:
  GRUB2 version 2.02~beta3-4ubuntu7.2 causes unbootable system

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  After updating to Gnu GRUB2 version 2.02~beta3-4ubuntu7.2, any attempts to boot the system flashes the loader menu for a split second and then crashes to a black screen with purple top and bottom border with the GRUB version at the top.
  I have attempted to repair-boot the system, but the same problem results.

  I have my EFI on /dev/sdb1
  Boot on a BTRFS /dev/sdb2
  Root on a BTRFS /dev/sdb3 Subvolume=@

  I have attempted to manually reinstall GRUB2, and the same problem occurs.
  This happened directly after the latest Ubuntu GRUB2 update and has been a problem for weeks now.  I have managed to boot Windows from my EFI thanks to my motherboard, but this clunky OS has me wanting to throw my PC.
  If someone could assist me in fixing this bootloader, I would greatly appreciate it.  Thanks!
