This is a quick tip for people that want to change Grub2 boot order in ubuntu 10.04 and 10.10. In Grub2 you can no longer edit menu.lst (sudo gedit /boot/grub/menu.lst) . Now the file we have to edit is Grub and is located in /etc/default/grub.

Here are the steps to follow:

1- To edit the grub file open terminal and type the following command :

sudo gedit /etc/default/grub

You will got something like this :

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_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=640×480

# 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”

Now to change the boot order, you need to change the GRUB_DEFAULT Entry, for example you have  windows7 in the 3rd position and you want to set it as default, to do that set default to 3:  GRUB_DEFAULT=3

2- Now update Grub using the command:

sudo update-grub

And is done!
