While using CWM recovery on my nook touch I foolishly used a tool that wiped my entire partition, how do I fix it?

My nook simple touch has been bricked by a tool designed to wipe all partitions that I found on a deep google search. I can still boot up into CWM and attempted to use the backup to restore my nook to previous conditions. Its obviously a vain attempt at this point to try anything else as I was capable to mount my internal nook partitions onto my ancient laptop. The nook's partitions show up as unallocated on gparted.
