I have a Logic Supply ML100G-30 that was recently running Ubuntu. I started to install Arch on it using a USB stick. The install started off fine. I verified that there was a pile of files in /sys/firmware/efi/efivars, so I believe I was booting in UEFI mode. The system had an existing EFI partition, so I didn't touch it; I just reformatted the main partition, /dev/sda1.
After running through everything in install.txt, I removed the USB stick and rebooted. The boot fails immediately with the message:
error: file '/boot/grub/i386-pc/normal.mod' not foundand then I get dumped to grub rescue mode.
I dug around using ls, but couldn't find normal.mod anywhere. I did find three filesystems, (hd0), (hd0,msdos1) and (hd0,msdos5). The first and last can't be read by ls (error: unknown filesystem). The middle one, (hd0,msdos1), contains what looks like a typical Linux filetree, including /boot/efi, /boot/grub and /grub, all of which are empty.
Here's what my partitions look like when I boot off the USB stick:
Disk /dev/sda: 238.5 GiB, 256060514304 bytes, 500118192 sectors
Units: sectors of 1 * 512 = 512 bytes

Units: sectors of 1 * 512 = 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytesI suspect what's happening is that /dev/sdb2 is not getting mounted properly, but I'm not sure how to fix that.
Any help would be appreciated.

After running through everything in install.txt
Hello and welcome to the forums.
"install.txt" - what is that and where is it from? Aren't you following the installation guide - https://wiki.archlinux.org/index.php/Installation_guide ?
It would probably help if you posted the actual commands that you used during the installation...

Hi, thanks for the welcome!
install.txt is a file I found at /root/install.txt when I booted off the USB stick containing archlinux-2017.06.01-x86_64.iso
It appears to be the text of https://wiki.archlinux.org/index.php/Installation_guide, so far as I can tell.
Your request for a listing of all the commands I executed is reasonable, but I'm afraid I don't remember every step. Is there a step that should have created normal.mod? My guess would be that it would only have been created, at least explicitly by me, in a step where I was changing the partition table, but all I did there was to reformat /dev/sda1 using mkfs.ext4, so that can't be it.

[OK about the install file]
As far as I am aware, /boot/grub/i386-pc/normal.mod should be automatically created when you install GRUB - perhaps double check you followed that part of the installation guide correctly. Did you remember to generate the GRUB main configuration file - https://wiki.archlinux.org/index.php/GR … ation_file ?
There is also lots of info about GRUB at https://wiki.archlinux.org/index.php/GRUB and UEFI: for instance it's "highly recommended" to use GPT partition tables and your output shows yours are "dos".
