Works perfectly in Debian 11 / Grub 2.06

GRUB maintainers should really add an option to natively deactivate this, it's really ugly, especially if you hide the GRUB menu : the Welcome to GRUB flashes for a fraction of a second, and only on a portion of the screen :

THANK YOU! My HP Elitebook kept freezing up on the "Welcome to GRUB!" message, great little script you've got here!

One question though, my system is UEFI with GPT, must I apply this script after every grub or kernel update, or does it apply to the EFI file somehow? I read your http://rabexc.org/posts/grub-shush but not all of it :P

My system wouldn't boot Linux via UEFI through the original EFI directory, so I am happy you have made it so we can specify the EFI file!

Weclome to GRUB! Still shows but the "loading grub" has been removed

Your idea is really great. But I would like to use your scripts not for quieting GRUB, but to change "Welcome to GRUB!" message to my own. Do you think it will be possible with your script? Could you give me a clue, what should I change in your scripts to allow changing GRUB message to my own? Thanks!

I have arch linux on my pc. I want delete Welcome Grub, but have error
make: cc: No such file or directory
make: *** [: mbr.o] Error 127

echo 0 > /sys/class/graphics/fbcon/cursor_blink
echo 1 > /sys/class/graphics/fbcon/cursor_blink

we need to add this somehow
because when the pc start the cursor still blinking

For those around here knowing how to properly rebuild a debian package,
it's worth knowing that inserting in debian/rules

FLICKER_FREE_BOOT := yes

before

ifeq ($(FLICKER_FREE_BOOT),yes)

will achieve a better result.

I'm eternally grateful for this neat and well-documented program

I wanted to remove the ugly messages but keep the formattable GRUB menu

grub-shusher makes more sense to me than the Arch wiki's recommended method of replacing grub with grub-silent: which shows me many thousands of lines of output for me to remove only 2 lines from the screen. grub-silent is a hammer to crack a walnut where this program is tight and specific

Some more ReadMe explanation would have helped me understand better but anyone running such a venerable program should hopefully read through these comments in case this helps anyone

The screens the "Welcome to Grub" message appears on flash up very quickly.
"Welcome to Grub" is hardcoded into the kernel.img but at the same time in the boot sequence there is also "GRUB loading." which is in the MBR (I guess it is generated an instant later, after a screen-refresh). This is one of the messages the second program removes. I'd have liked the ReadMe to have listed what "MBR" (the second program) does as thoroughly as it does for grub-kernel. Since I was conscious I only wanted part of what the program was designed for.

In Arch the method to get pacman to auto-apply the changes will be different from the instructions for Debian+apt. I didn't try that yet.
