GRUB not showing

Support
#1

I have this problem where, If i don’t turn on my monitor between the following:
Right after boot → Before my pc starts loading grub

My monitor will be black, but i can interact with grub on my keyboard as if it was running. (example: press the down arrow a lot of times and then enter, will run the last entry in grub menu)

If i turn on my monitor before boot/have left it turned on and boot my pc, it doesn’t show, (Just black screen).

This seems to be cross-distro as it happened while I were on Arch linux too.

Maybe i configured something wrong?

I have the exact same issue.
I’m using manjaro 20.1 cinnamon, and now i installed windows 10 to dual boot.
I reconfigured grub, but that didn’t help. As you said, i can interact with the grub menu while the screen is black.

Same issue on my installation - Manjaro 20.2.
I’ve tried the advice from @stephane, even I’ve enabled the sound on GRUB start (GRUB_INIT_TUNE="480 440 1") but no luck. On boot, I can hear the sound and there is the black screen as well. If I navigate with the arrow keys, if feels like something is happening in the background and when I make some combination with them, it redirectes me to the BIOS menu.

Bump for the visibility. Maybe someone more experienced will have additional questions.

Thanks for this, it sorted the issue of grub not showing, now I have to figure how to add my windoze drive that I use for gaming to grub to show up again as that has disappeared from the menu…

  • If you need dual-boot you can reactivate os-prober the easiest with the following command combination in a terminal:

echo GRUB_DISABLE_OS_PROBER=false|sudo tee -a /etc/default/grub && sudo update-grub
