From the comments:
Me: Does it show a text-based Ubuntu loading screen on a black
background?
You: yes exactly that. it shows that and the gnome screen at the same
time, only glitching where the text is, but the system after boot
works just fine Edit: only shows about 5-10 lines and boots in to the
log in screen
Don't worry about it at all. That simply means that the kernel upgrade broke KMS, which was a feature only very recently added anyway. All that means is that the driver handoff for the boot screen isn't working properly.
But, that has ZERO effect on anything after the system is booted. So you're fine.
If you want to try to fix it, you can try following this answer, but as always, no guarantees.
