(SOMEWHAT SOLVED) grub2 finds and boots windows 7 but NOT arch

I installed arch on a new system. I have 64-bit Windows 7 Ultimate. I installed arch skipped bootloader, chrooted into system and installed grub2 and installed. My system is btrfs. I do not have a seperate swap or home partition. OS-prober is installed. I have another system with btrfs and grub2 and all works fine. When I run grub-mkconfig -o /boot/grub/grub.cfg I get this

Keyboard is not working properly on other computer so I cannot insert code brackets.

Found linux image: /boot/vmlinuz-linux
Found initrd image: /boot/initramfs-linux.img
No volume groups found (what does this mean)
Found Windows 7 (loader) on /dev/sda1
done

Again boot and root partitions are btrfs. Grub2 is the bootloader and it does support btrfs at least the version in the repos a month ago did. I have feeling this might be the problem but I do not know why. Windows 7 boots successfully by the way. No Arch Linux

Edit: Backed up boot partition. Made the partition ext4 and cp'd it all back and still no luck. I converted it because ran the grub-mkconfig again and I got everything above but also I got an unknown filesystem error. Converting it back to btrfs...

Edit 2: I am writing this from within windows but grub2 now shows Arch in the the menu. (no gui on this install yet) After what feels like 100 grub-installs and grub-mkconfigs it is all working. I still have two questions. For like half a second I see a file not found and I think it is a *.mod in /usr/lib/grub/i386-pc directory. (i have good eyes). What could this be? Secondly, what does no volume groups mean? Marking this somewhat solved.

The "No volume groups found" is normal, I think. At least, I get that too. I would guess that it means you're not using logical volumes but I don't know for sure - I just assumed that's what it meant when I saw it. I figured it had to do with /etc/grub.d/20_linux_xen - maybe?

The logical partition thing make senses.

I'd just ask checking the grub.cfg file to see if the device id entries for arch in the grub menu are correct.
In my case, I use ubuntu's grub2 and each time I have to update grub for some reason, it wont get the partition right for the arch entry.
