My laptop doesn't want to work with GRUB, but it works fine with rEFInd and manjaro. But now I want to install Ubuntu and I don't know how to make it immediately install rEFInd. Maybe someone knows how to do this? (sorry for my english it's all google translate)
I suppose you want to know where the option to select Device for boot loader installation is at when installing Ubuntu.
Let me know if this works for you.
