I tried to upgrade from 12.04 -> 12.10. The install seemed to go well but upon reboot, I get the grub recovery console.

I tried to reinstall using the boot-repair Boot Repair

which usually works a treat. However this time it says it is scanning my HDD and never recovers.

When I try to reinstall grub from the liveDVD using the old 

    grub-install <dir> <dev> --recheck --debug &> gruboutput.txt

I get this

Pastebin link

I think it should be installing to dev/mapper/isw_gbaaebhfe_Volume0 even when I made --> dev/mapper/isw_gbaaebhfe_Volume3

Any help would be appreciated

Create Boot-Repair-Disk would be better option. You can download it here.

IF you fail to see the Grub:- Insert a Ubuntu 12.10 Live-CD/DVD and run the following commands:

$sudo mount /dev/sdXY /mnt # XY is the drive, eg. sda or sda1

$sudo chroot /mnt

$sudo grub-install /dev/sdX #X is drive number

$sudo update-grub # Note that you just need to enter the 'drive' identifier here, not the partition!

Reboot and take out the LiveDVD. Lemme know if it doesn't work as intended.

you can also have ultimate boot cd on hand run super grub it will allow you to boot the os then run sudo update-grub from the os
