When I start my Ubuntu there is this splash screen:

enter image description here

and i got rid of it by changing this line:


so it skips the grub right away.

But if I force reset/power off the machine I get this screen:

enter image description here

Now with 30 seconds countdown...

My question is where is this coming from, which file? I want to change it and it's not in /etc/default/grub


I found it on my own

in file /etc/grub.d/00_header

line 333

set timeout=${GRUB_RECORDFAIL_TIMEOUT:-30}

I have added this variable in /etc/default/grub file


and now even if i force reboot/power off it will skip the grub

  • you could also try in your grub setting GRUB_RECORDFAIL_TIMEOUT=N not sure which one of those overwrites which. But if the setting in the grub file works it's probably better than changing the header file. – Ziazis Jul 6 '17 at 12:50
  • I think that wouldn't work because of this if [ "\${recordfail}" = 1 ] ; then set timeout=${GRUB_RECORDFAIL_TIMEOUT:-30} else EOF in header it is strictly set so i think it would be overwritten. But i will try it out now and let you know – lewis4u Jul 6 '17 at 12:51
