I don't understand this. Updating the system requires that it be
running, in order to download the packages, and install them. Is this
some kind of GUI functionality? Did you power down the system during
the update? Have you successfully performed an update like this before?
I don't understand what it is either. I think it may have been new with F25. I don't believe I had ever used it before.

This sounds like the boot record for grub on the drive was damaged. Or
the location it is pointing to in no longer valid.

Something has damaged the filesystem from the sounds of it. I wonder
if it is just a coincidence that this happened during an update.

Is it possible the drive has gone bad?
Is there a way for you to boot a rescue CD or a live CD (or USB)? Then
you could run diagnostics / investigate from a running system.
Yes, I set up a F26 boot usb and just installed F26 on top of the existing root. It boots now; the grub options at boot are all messed up but I can work on that.
Thanks for the good suggestions!
