I was using the GUI option since the manual option requires you to know the index of the Windows entry upfront (index starting at 0, for me Windows was at index 5).
This is what I did:
- Start a Terminal (search for 'Terminal' in one of the topmost icons), then paste/type this into the terminal: sudo add-apt-repository ppa:danielrichter2007/grub-customizer (enter password) sudo apt-get update sudo apt-get install grub-customizer grub-customizer (program comes up) - click Preferences - select Windows as default - Close - Save - close the program - restart to test it, done
