New Install Won't boot after GRUB

Question

I have been using ArchBang for the past year and a half so I finally thought that I knew enough about Linux to try installing a true Arch Linux system. 
I followed the beginner instructions carefully and was able to successfully install my system (or at least I thought) and GRUB.  I am currently running my system on a Dell inspiron with two separate hard drives.  The primary drive is the one I am trying to install Arch on while I have Windows 7 installed on the second drive.
The drive I installed Arch on is /dev/sde.  I think that I successfully installed GRUB given that when I boot my computer it goes into GRUB and shows both my Arch Linux install and my Windows 7 system and when I select Windows 7 in GRUB it successfully boots.
But when I selected my Arch install in GRUB the system does not boot.  It just shows:
/dev/sda1: clean, 31087/3751936 files, 478966/15000685 blocks
and then I am left with a blinking cursor and after a few minutes I get:
Welcome to emergency mode. Use "systemctl default" or ^D to enter default mode.
Give root password for maintance:
Anyone one how I fix this?  Do I need to reinstall?  As I said before I didn't receive any errors during the install and GRUB seems to be working correctly. Please remember that I am a newbie but please help!

No you don't need to reinstall, you do need to fix your grub configuration though.  It sounds like it is not properly pointing to the root partition.
Post your grub config and your partitioning scheme.
Partition Scheme from lsblk output:
Name         MAJ:MIN        RM        SIZE        RO        TYPE        MOUNTPOINT
sda             8:0                  0           931G       0            disk       
  sda1         8:1                  0           57G         0            disk           /
  sda2         8:2                  0           7G           0            disk
  sda3         8:3                  0           866G       0            disk
sdb             8:16                0           111G        0            disk
  sdb 1        8:17                0           111G        0            disk
sr0             11:0                 1           1024M     0            disk
I don't now if this output of the partition table is what you want given that the lsblk is the only command I am familiar with.   The sdb disk is where the windows install is.
Here is the /boot/grub/grub.cfg file:
