So, last night, when shutting down the laptop, there was a prompt to install updates and then poweroff so I did that. Next thing I know, when I boot my laptop, I get the grub rescue prompt. Here's what I know so far:
grub rescue> set
cmdpath=(hd0,gpt1)/EFI/ubuntu
prefix=(hd0,gpt3)/boot/grub
root=hd0,gpt3
I tried to do:
linux /boot/grub/vmlinuz-4.15.0-34-generic root=/dev/sda3
and I get:
Unknown command `linux'.
I've also tried to:
insmod /boot/grub/x86_64-efi/linux.mod
but I have not had any luck loading linux. I can't do normal.mod either nor boot. I'm stuck here and need some help on how to boot so I can do grub-install. There's no other OS on the laptop and my home directory is in a different partition, for what its worth. Please help me recover my Ubuntu.

There is no output. It's as if it went through without problems. I still get Unknown command afterwards.

My problem has been resolved. I loaded a live USB session of Ubuntu 18.04 and installed the Boot Repair.
https://help.ubuntu.com/community/Boot-Repair
Using the Recommended repair option reinstalled grub with the shim.
