I use Ubuntu GRUB.
After installing some other Linux distribution Ubuntu GRUB disappears and the other distribution's GRUB appears.
How can I recover the Ubuntu GRUB?

sudo grub-install /dev/sda
And you may be able to turn off the other install from reinstalling its copy of grub. But these instructions are for Ubuntu: http://askubuntu.com/questions/503417/how-to-prevent-ubuntu-from-overwriting-grub-bootloader-after-update – oldfred Feb 06 '17 at 16:54
