[Bug 1332211] [NEW] The "--disk-module=MODULE" option of "grub-install" don't work in Grub 2.02~beta2-9

[Asuna]

Public bug reported:

My OS is ubuntu14.04 LTS.
And the command "grub-install -V" shows that the grub version is Grub 2.02~beta2-9.

Since I have two disk on my laptop, and one of them is not bootable, I
have to use nativedisk mode.

But the "--disk-module=MODULE" option of grub-install can not work normaly.
Command like:
sudo grub-install --disk-module=native /dev/sda

returns me the following message:
"
 --disk-module: (PROGRAM ERROR) Option should have been recognized!?
Try 'grub-install --help' or 'grub-install --usage' for more information.
"

What's the meaning of "should have been recognized", not unrecognized?

Grub(-install)2.00 in ubuntu13.10 don't have this bug. Everything goes
well.

The following attachment is the output of `sudo fdisk -l`. /dev/sda is
SSD, /dev/sdb is HDD and because of the bios problem, it's not bootable.
