Method to install Grub Customizer [Ubuntu/Elementary]

I fresh install of win10 and elementary OS, want customizer. My PC is booting into elementary by default instead of into win10. I use both, but I want o boot into win10 by default. This is method to install Grub Customizer in Loki (maybe in other Ubuntu/Debian Linux OS).

sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer

If get error:

add-apt-repository: command not found

For Ubuntu 14.04 or 16.04 you need another package:
sudo apt-get install software-properties-common
