Run into issues moving an installation.

Question

A few months ago I put a fresh install of arch on my laptop. I used an lvm in an extended partition, and used luks.
I have a dual boot with windows 8.
As I needed to give windows 8 more space I decided to backup my install and repartition the drive. I have now copied the backup to the new partition layout (not encrypted and using regular mbr partitions), used the livecd to change the fstab, the mkinitcpio, rebuilt initramfs and fix grub.
On booting I get dropped to the emergency shell with a few systemd errors, mostly about systemd-udevd, worker did not accept message.
Any ideas? Is this recoverable?
EDIT: I've managed to get at least some of the exact messages that show up:
[FAILED] Failed to start Remount Root and Kernel File Systems.
See 'systemctl status systemd-remount-fs.service' for details.
[FAILED] Failed to mount Huge Pages File System.
See 'systemctl status sdev-hugepages.mount' for details.
[FAILED] Failed to mount Debug File System.
See 'systemctl status sdev-hugepages.mount' for details.
[FAILED] Failed to mount POSIX Message Queue File System
See 'systemctl status dev-mqueue.mount' for details.

[OK] Started udev Kernel Device Manager
[FAILED] Failed to mount /tmp.
See 'systemctl status tmp.mount' for details.
[DEPEND] Dependency failed for Local File Systems.
Welcome to emergency mode! .......
EDIT2: Ok, this is getting stranger.
If I run cfdisk I get: FATAL ERROR: Bad logical partition 6: enlarged logical partitions overlap.
I'm going to delete and re-create the partitions that I've changed and see what happens.
EDIT3: Ok, so I've re-created the partitions, synced from the backups again and made the necessary changes.
I get the same errors as above. I managed to get hold of some of the journald output:
From journalctl the main errors are now:
systemd-udevd cdrom_id --lock-media /dev/sr0 terminated by signal 15
systemd-udevd ata_id --export /dev/sda terminated by signal 15
systemd Failed at step EXEC spawning /bin/plymouth: No such file or directory
systemd-udevd timeout, giving up waiting for workers to finish
Unit systemd-udevd.service entered failed state
Any help would be appreciated. I'll probably reinstall if I can't get it fixed by tomorrow afternoon.

Do you still get the cfdisk error?
Post fstab, listing from cfdisk (e.g. fdisk -l /dev/sda or whatever) as relevant and boot loader config file. Also mkinitcpio.conf.
As I deleted and re-created the partitions I no longer get the cfdisk error.
fdisk -l /dev/sda/ :

EDIT: Just to clarify, I still get the errors in the first post. I haven't needed to use the arch install on the machine in the last few days as I'm working almost purely on my desktop at the moment. I'll need the install working by Christmas though so I'll wipe and re-install then if I still haven't found a solution.
