I was given this after renaming my /boot/grub/grub.cfg to /boot/grub/happy.cfg instead.
This isn't really an error message, it's a Command Line Interface, ('CLI' for short).
Since GRUB couldn't find the /boot/grub/grub.cfg that it needs to give me my usual GRUB Menu.
Solution 1: Boot with CLI mode commands, CLI Mode Commands
Solution 2: Use CLI Mode command to get GRUB Menu

I was given this error message after trying to boot a USB flash memory stick when it was not plugged in.
Commands used were:
If you have this error, first check to make sure you are trying to boot the right disk.
Is you disk plugged in (correctly)?
If it's a hard disk, does it sound like it is spinning up okay?
Is it recognized properly by the BIOS?
nice new feature of GRUB2 is the ability to go back to the previous
menu after pressing any key. The 'Esc' key would be the best choice.
