Change Default Boot Order for Grub 2 in Ubuntu 11.04 Natty or
10.10, 10.04 etc
Ubuntus 9.10, 10.04, 10.10, 11.04 etc. use Grub2 so if your are
using any of these versions of Linux then this trick should work
for
you. This post discusses the standard command line approach as
well as GUI approach, discussed at the end of this post.
With Grub 2 you can no longer edit grub.conf or menu.lst files
located in /boot/grub folder. The file to be edited is now
"grub"
located in /etc/default/ folder, you can edit it by running the
following command from terminal (sudo gedit /etc/default/grub).
The
contents would look like this:
If you change this file, run 'update-grub' afterwards to
update
# /boot/grub/grub.cfg.
GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo
Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
# 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
entrys
#GRUB_DISABLE_LINUX_RECOVERY="true"
To change the default boot option, you just need to change the
GRUB_DEFAULT parameter. 0 is the first entry, so if you want
windows to be your default boot option which is, say at, 6th
position in the grub menu, then you just need to change
theGRUB_DEFAULT value to 5 and save the file and close it. If you
want to change the Auto Boot preset time then you would need
to change the value of GRUB_TIMEOUT parameter, it should be
assigned a value in seconds and would determine the delay in
seconds before grub boots the default choice, automatically. Now
from the terminal run following command and your grub default
boot order would be changed when you boot the next time:
sudo update-grub
GUI ApproachJust install the startup manager by using synaptic
or running the following command
sudo apt-get install startupmanager
