My ubuntu is booting to the Grub command line.

I have Ubuntu 16.04 installed on my workstation. I haven't used it for the past ~2 weeks. I think 2 weeks ago I updated the software from the Ubuntu software popup thing, so that could be causing my present issue.

I've research into this problem but can't seem to find a solution to my specific problem. Specifically I looked at After update in Ubuntu 16.04 I ended up in GNU GRUB and appear to be stuck there And several others.

As you can see from the linked image, the only existing filesystem is on (hd0,2), but this is showing as a fat system which is not compatible with Ubuntu. Could my Ubuntu have been wiped somehow? Any advice on how to proceed?

To check the file system on your Ubuntu partition...

  • boot to the GRUB menu
  • choose Advanced Options
  • choose Recovery mode
  • choose Root access
  • at the # prompt, type sudo fsck -f /
  • repeat the fsck command if there were errors
  • type reboot

If for some reason you can't do the above...

  • boot to a Ubuntu Live DVD/USB
  • open a terminal window
  • type sudo fdisk -l
  • identify the /dev/XXXX device name for your "Linux Filesystem"
  • type sudo fsck -f /dev/XXXX # replacing XXXX with the number you found earlier
  • repeat the fsck command if there were errors
  • type reboot

Update #1:

The user's computer is booting up to a grub> command prompt, not a GRUB menu.

Update #2:

Ubuntu is not installed on /dev/sda, and /dev/sdb is totally empty. Somehow /dev/sdb got wiped.
