How to change the default menu item in Grub?
The line GRUB_DEFAULT=0 means that GRUB will select the first menu item to boot. Change this to GRUB_DEFAULT=saved. This change will make it easier to change the default item later.
Use the arrow keys to select a boot option and hit the ‘e’ key to that entry’s boot options by hand. You may need to do this to run a specific boot parameter, pass a kernel flag, adjust the run time level or set the frame buffer mode. When you’re ready to boot with your modified changes press Ctrl+X.
