The GRUB shell is not equal to bash. It is a small shell which
implements the commands listed by the "help" command. The only form of
TAB completion it offers is completion of GRUB commands. E.g. when you
type "partn" and hit TAB, it completes to "partnew". Or when you enter
"con" and hit TAB, it completes to "configfile".

When you _boot_ your system into GRUB and enter the command-shell from
there as opposed to starting the GRUB shell from within a running
Linux OS.
