Change GRUB timeout and default option on Ubuntu 12.10

  • SumoMe

If you use one PC with Ubuntu and other OS, sometimes maybe we need to change timeout of the GRUB before load OS or order of all OS. I will show you how to do that on Ubuntu 12.10
Open terminal /shortcut Ctrl+Alt+T/.
In terminal enter

gksudo gedit /etc/default/grub

Enter your password and you will see grub file in gedit editor.It will be something like that

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
  • GRUB_DEFAULT – default is 0 it corresponding to the first value in the grub menu loader. So for second option is 1, third is 2 and etc. In my case Windows 7 is 5 option in grub menu so I set GRUB_DEFAULT=4
  • GRUB_TIMEOUT – this is the option how many seconds to wait before start loading the selected option. Default value is 10, as you can see upper I change it to 30 seconds.

When you finish with editing save the document and close it. In the terminal enter this command to apply changes that you made.

sudo update-grub

Reboot and you should see your default and timeout options change.
