Public bug reported: This is the second time that I have the same issue - in the span of 24 hours. I tried to update my linux and came across this issue. After restart of my computer, I won't be able to reboot and it would remain at Grub2 bash, attempt to bring it back to life through grub bush was to no avail.
The machine is a Xeon process, Dell Precision 470.
