My Ubuntu 18.04 loads really slow. At first the GRUB menu always showed for 30 seconds on every startup. Fiddling around with 

/etc/default/grub

was little help. I found the suggestion to run

sudo sed -i "/recordfail_broken=/{s/1/0/}" /etc/grub.d/00_header

Now the GRUB menu doesn't show, but instead there is a blank screen for 10 seconds before the system starts. The problem is that I am not sure what the above command does, so now I don't know how to reverse it and I still haven't solved the slow boot problem.

The command 

sudo sed -i "/recordfail_broken=/{s/1/0/}" /etc/grub.d/00_header

replaces the string recordfail_broken=1 with recordfail_broken=0 in the file /etc/grub.d/00_header

To revert the change, you can run

sudo sed -i "/recordfail_broken=/{s/0/1/}" /etc/grub.d/00_header

which will do the opposite of the former command, it replaces the string recordfail_broken=0 with recordfail_broken=1 in the file /etc/grub.d/00_header

You will have to run sudo update-grub to make the change take effect.

The suggested solution you mentioned is a workaround and is not a clean solution. You should investigate why the problem appears. I think that the origin of your problem is that your /boot-directory resides in a filesystem Grub can't write to, e.g. btrfs.

  • Thanks! I also solved the solution with the grub menu: I just had to add GRUB_RECORDFAIL_TIMEOUT=0 in /etc/default/grub – Kikkomann Sep 13 '19 at 07:41
