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_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
# Uncomment to disable graphical terminal (grub-pc only)
# 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’
# Uncomment if you don’t want GRUB to pass “root=UUID=xxx” parameter to Linux
# Uncomment to disable generation of recovery mode menu entrys
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:
And is done!
