This may be the wrong subreddit, but a few hours ago I installed Ubuntu 16.04 to boot alongside windows and I restarted but there is no grub, it just snaps back into Windows 10, every option I found online about did nothing and just goes back into 10.
I have a Gigabyte GA-78lmt-usb3 6.0 motherboard.

Partition 1 is Windows, Partition 2 is Ubuntu, Partition 3 is swap, Partition 4 is Windows Recovery.
