System Bootorder not found - grub menu disappeared

(1/2) > >>

Using LL 5.2. Several updates were installed today and after the required reboot, in addition to the grub menu screen disappearing, the message, "System Bootorder not found. Initializing Defaults." began to appear. The PC however did boot. Checking Grub Customizer, the show menu box was still checked. Following the instructions in the last post of this thread...


...I was able to make the, "System Bootorder not found. Initializing Defaults." message disappear. However, the grub menu screen still does not appear, even though the show menu box remains checked. Searching for a way to fix the issue I found this:


However, the change suggested in the article is already in place on my PC. The change likely having been made because of the Grub Customizer setting for show menu.

A couple of additional notes. After some updates a few days ago I had to ditch the 4.4 kernel that I was using (so that the micro SD reader would be recognized) because of a kernel panic and a non-booting system. I'm now using 5.4, without a working micro SD card reader. Also, the Shift and Esc keys do not now, nor did they ever, make the grub menu screen appear on this PC.

Any ideas on what I can do to make the grub menu screen appear again ?

Could you post the output of the following terminal command?

cat /etc/default/grub

in order to give you an apporpiate answer.

Hope this help, regards

Thank you for the response. Here is the output:

cat /etc/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_DEFAULT="Advanced options for Ubuntu>Ubuntu, with Linux 5.4.0-72-generic"
GRUB_DISTRIBUTOR="`lsb_release -i -s 2> /dev/null || echo Debian`"

Hi, I do not way you have several lines different. I post the difference in the /etc/default/grub
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`

Also you have to uncomment
whether you are experiencing troubles with your boot process.
It was disabled by security purposes but I think you must check this. Are you dual booting with Windows?

Hope this help, regards

Thank you for the response. I'm not dual booting, LL is the only OS.

The only changes made to grub have been by either the original install, LL updates, or Grub Customizer. When I installed LL the grub menu was not showing and no key combination would make it appear so I installed Grub Customizer, checked the show menu box, and the grub menu began to appear. Several days ago after installing some updates and rebooting, the grub menu disappeared, even though the show menu box is still checked in Grub Customizer.

Why did the grub menu disappear ? Clearly something in one of those updates made it disappear, but another question is, why isn't Grub Customizer making the menu show ? It's likely that I'll not find the answers to either question.

After some additional poking around on the Internet I found an article that said uncommenting this line...


...would make the menu appear.

That worked and the menu is now appearing at boot. However, it's a bit different as it's monochrome, and there's no feather, but I guess that's to be expected from a console version. But, the above questions remain unanswered.

Given the issues I've had with this PC, micro SD reader only working with the 4.4 kernel, having to ditch that kernel due to an update, and now the grub menu disappearing for an unknown reason, I'm going to have to go back to Windows on this PC. It will run much slower, but, I won't have these issues.

LL will remain installed on a Dell PC that I have, it's one of those that came with 2 GB of ram and a 32 GB eMMC hard drive. In addition to LL I installed a 4 GB ram chip and that PC now flies. I've had no issues at all with LL on that PC, everything just works right out of the box.

Thanks again for your responses, I appreciate it.
