Setting up a mining machine with Ubuntu 12.04 LTS and sometimes during a reboot the machine will get stuck at the grub menu and you physically have to press a button on the keyboard to reboot. This is major issues if you are using a headless miner and do not have access to the machine. We want it to reboot and start mining with no downtime.

To do this, open up terminal and type: sudo nano /etc/default/grub
In this file, Add a line with this assignment: GRUB_RECORDFAIL_TIMEOUT=N
Set N to the desired timeout in case of a previously failed boot.

 

Next type sudo update-grub
