I upgraded both OSs yesterday and have been going through some odd behavior on Ubuntu's end. First the 'Security Boot Fail' screen was popping, so I disabled Secured Boot which solved that issue. However, now when I boot up a black screen shows up (formerly purple) and has all these boot options that were never there before:
Here is a copy of the boot-repair pastebin, which i've noticed sda3 is failing to mount.
Last but not least, i'd just like to include an image of my GParted for reference.
I googled all day yesterday, and I think i'm too novice to understand precisely what the issue is. I appreciate your patience!
