How to load Ubuntu Server automatically in Grub

  • 772

This is my /etc/default/grub:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX=""

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console


# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

But when I have a power failure, then the Ubuntu Server 12.10 stays at this screen. I've tried to solve it editing grub but doesn't seem to have an affect. Since I don't have display attached, I need it to start automatically Ubuntu every time.

Thanks!

    Edit /etc/grub.d/00_header and change line 236 (this line is in the make_timeout () function) to:

    set timeout=0

    1. For timeout=-1, there will be no countdown and thus the menu will display.

    2. For timeout=0, menu will not display even for a failed startup.

    3. For timeout>=1, menu will display for the specified number of seconds.

    Run sudo update-grub after the change have been made. Special thanks to McCunha on Ubuntu Forums for the above tip.

    The above change, however, still causes GRUB2 to boot into text graphics mode. Thus, an additional change is required. Edit /etc/grub.d/10_linux and change line 188 to:

    set linux_gfx_mode=keep

    Once again, run sudo update-grub after the change has been made.
