(Optional) Configuring the GRUB Timeout

Scenario

For Ubuntu 14.04 or Debian, you need to set the GRUB timeout to prevent system login failures caused by unexpected power-off. For other OSs, skip this section.

Procedure

  1. Use the vi editor to open the /etc/default/grub file and appendix GRUB_RECORDFAIL_TIMEOUT=10 to the GRUB_CMDLINE_LINUX field.
    GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=2
GRUB_DISTRIBUTOR='lsb_release -i -s 2> /dev/null || echo Debian'
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX="console=tty0 console=ttyS0"
GRUB_RECORDFAIL_TIMEOUT=10
  2. Run the following commands to update the configuration:

    grub-mkconfig -o /boot/grub/grub.cfg
