Dual boot Ubuntu 16.04/Windows 10 - monitor issues

[darksurfer11]

I have an MSI GE72 2QD Apache Pro currently with a Ubuntu/Windows dual boot setup. The issue is when I am in Linux, both my built in display and an external display work, however, outside linux (including the bios) the build in display does not work.

I just got off the phone with their tech support and they tried to tell me that because I have a dual boot setup (single drive with two partitions) it is confusing their bios and causing my issue....This seems absurd to me, but I wanted to run it by here. Is this legit?

Update: removed Linux and now only have Windows on the internal drive, built in screen still doesn't work. It only works with Linux right now...

Also, ran furmark on the GTX960, no issues running at 1080P for about 2 minutes
