[Bug 1965689] Re: Black screen instead grub menu at boot

Thanks, tried both workarounds but with no success.

Didn't mention before but switching on my computer I can still get the
EFI boot menu pressing F12. From there I can select any other system and
set one of them as the default system at boot.

Title:
  Black screen instead grub menu at boot

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  Fresh install of Ubuntu 22.04 on multi-boot system.

  Steps:
  1. Switch on computer.
  2. You see for about 10 seconds a black screen instead GRUB MENU.
  3. After 10 seconds Ubuntu boots normally.

  Extra tests:
  - During the 10 seconds of black screen, I can press ENTER and Ubuntu will boot.
  - I thought that maybe grub menu was just not visible but still there, so I've tried to use "arrow keys" (up and down) to select a different system and then press Enter... but nothing happened, the screen remained black.
