This same type of error is occurring with DOS style partition tables.

# grub-install --recheck /dev/sdb
grub-install: error: cannot open `/usr/lib/grub/i386-pc/msdos.mod': No such file or directory

This was working a few days ago.

Further testing indicates that the file it's actually wanting is part_XXXX where XXXX is either the msdos.mod or gpt.mod. Trying to track down the change responsible for this.

Appears to be the generated grub-mkimage command that is wrong. Manually running the command with the correct entry (part_msdos.mod or part_gpt.mod) seems to work. Still looking for the actual change responsible.

I can confirm this bug as well with this new version of grub.

Found the same problem when trying a fresh install

The same problem here. msdospart.mod and part_msdos.mod are there, but there's no msdos.mod.

Edit 0: This is not a GPT system, it's a plain old BIOS layout (both in terms of firmware and partitioning). But I have the same problem, just s/gpt\.mod/msdos.mod/
Edit 1: As a stupid workaround, I did cd /usr/lib/grub/i386-pc/; ln -s part_msdos.mod msdos.mod; and it helped, i.e., GRUB installed itself and my machine survived a reboot. That's not a permanent solution, but it might come in handy if you desperately need to install GRUB right here right now.

Same problem here. I've tried:
ln -s part_gpt.mod gpt.mod

Now grub installs, but the system doesn't boot:

It says something like:

Module part_gpt.mod already loaded.
Aborted. Press any key to exit...

What harmless module can I link from gpt.mod to recover my system?

Looks like we have to apply parts of commit f585c905054b8c74e6e0a67341e84accfb816912 (fix partition module names when /boot is on diskfilter).

I've build my package with the attached patch. It also fixes two other bugs currently open.

Grub 2.02-beta1 has been tagged in git... Perhaps this is a good chance to update the package to something different than just a random git commit.
