Not sure if this is the right place for this but I'm at a loss on where to look/ask for help. I recently installed Ubuntu 16.04 GNOME and after many hours of many many problems I've finally got it running. However there's a problem. I have Windows 10 installed on a separate drive and I need to be able to switch between these quite quickly, which normally wouldn't be a problem. However, Ubuntu's splash locks up and if I run it with nosplash there's just a black screen after it loads. To fix this, I switch the initial display device in the BIOS to the integrated intel chipset. Once I do that Ubuntu runs fine, but for some reason I don't have access to the BIOS anymore. No prompt to press del/F12, if I try to open the BIOS settings from grub I just get a flashing cursor in the top left and nothing happens. So right now my choices are to run Ubuntu, and only Ubuntu, just fine, unable to switch boot devices at any point unless I reset the CMOS, or Ubuntu doesn't work. I have a Gigabyte GA-Z97-HD3 motherboard and Nvidia GTX 1070 GPU. I have checked that quick boot is disabled, and it is, and I have up to date drivers for the GPU. Any help would be appreciated, I'm really excited to start using Linux for development again, but as an avid gamer, having it as my only OS is just not an option.
