Was running High Sierra perfectly with my GTX 1050, tried booting with the integrated GPU to see if it was worth the loss of dual screens to upgrade to Mojave, booting back to High Sierra with my NVIDIA GPU now won't work.

Title pretty much says it all. - I had a perfect setup with my NVIDIA GTX 1050 GPU - I tried booting with the IGPU (nv-disable=1, turned on Intel injection, turned off "Use NVIDIA WebDrivers) - Decided not to upgrade and stay on High Sierra with my NVIDIA GPU - Tried to boot - Stuck just before the lock screen shows. http://imgur.com/a/3S54nSp

Note: The IGPU log entries always came up, even before my system broke. I'm not sure why, since I'm not using it.
