I recently install arch (hopefully successfully) on my machine. When I went to reboot however I had a problem. I got a black screen with text saying

Grub loading.
Welcome to GRUB!
error: file '/grub/i386-pc/normal.mod' not found.
Entering rescue mode...
grub rescue>

I have since googled looking for an answer. I almost found one here on the Ubuntu forums yet then I saw one of the comments saying it was untrue. There is also another answer but I'm not sure if I want to install from the live CD for fear of messing things up.

You would understand my fear if you too spent 7 hours setting this up after constantly running into partitioning, command, tutorial, and system problems. What a joy.

Anyone know of an easy solution to getting grub working?

The second suggestion (with the liveCD and chroot) is probably worth trying. Or a variation on it: I'm not an arch user but have installed it before, and from what I remember, you might want to contemplate that suggestion in relation to the various stages of installing arch, some of which involve a chroot. If you can backtrack to a previous step booting the arch CD and then mounting and chrooting into your installation, you should be able to try grub-install. You don't have to repeat any of the steps, just use them as a guide to get chrooted in from a liveCD. –  goldilocks Mar 29 '13 at 19:26
While I'm not at the computer right now I do believe I tried the grub install and it didn't work.- –  Griffin Mar 29 '13 at 19:34
@Griffin It didn't work as in "grub-install" failed, or it didn't fix the problem? –  derobert Mar 29 '13 at 20:09
@derobert grub-install wasn't a valid command\ –  Griffin Mar 29 '13 at 20:21
@goldilocks Second one isn't working either –  Griffin Mar 30 '13 at 0:40

I just had this problem today after a fresh install of Mint 15.

The installer created /boot/grub/x86_64-efi modules but not the regular /boot/grub/i386-pc modules.

A re-installation of Grub from the Live CD fixed the issue.

Replace /dev/sda and /dev/sda1 with your boot device and boot partition and run the following commands from the Live CD:

sudo mount /dev/sda1 /mnt
sudo grub-install --boot-directory=/mnt /dev/sda
sudo reboot

Haha! Thanks James but I've moved on. Sorry but I won't be able to test if this theory is true. –  Griffin Aug 3 '13 at 21:43

A really annoying thing...

As apparently the directory /boot/grub/i386-pc was simply not in place, I finally solved the problem by copying the whole /usr/lib/grub/i386-pc to /boot/grub. That's all.

cp -r /usr/lib/grub/i386-pc /boot/grub
