On my MSI B350 Tomahawk motherboard, I dual boot Windows 10 and Ubuntu on the same drive. It automatically boots into Win 10 and only boots into Ubuntu's GRUB if I go into the boot menu by pressing F11. I want it to go to GRUB by default, but it seems to only go into Windows if I don't intervene in the boot menu. Ubuntu is loaded on a separate drive partition, and I was wondering if there was a way to make it boot to Ubuntu for GRUB to select which OS I want to use by default.
