GRUB disables timeout on failed boots

Jasun -

By default GRUB is set to disable the countdown for auto boot when a system does not fully shutdown properly.

This is great for physical servers as it prevents a reboot loop for failed hardware and other issues.

However, in a Cloud environment, this is not ideal.

To disable GRUB from halting on failed boots add the following line to /etc/default/grub:

GRUB_RECORDFAIL_TIMEOUT=2

Then save the file and run the command:

update-grub

 

There is no need to reboot your system.

 

NOTE:
This will only prevent GRUB from not halting auto-rebooting. 
If an issues exists that is stopping your system from booting,
this will need to be addressed by your systems administration team.
