System will not boot!

I unplugged my computer to do some cleaning at my desk and when I plugged it back in I could not longer boot into Ubuntu 18.04.

It sits for a minute and a half and goes into emergency mode. I ran the journal and it says:

timed out waiting for device dev-disk-by\x2duuid-246A\x2dED7E.device

Which I believe is my boot drive which is a SDD.

It then says:

dependency failed for boot/efi, Local file systems and for clean up.

Please help!
