Solution:1

There is an ISO in the root of your E:\ 'drive'. Wubi has some logic that looks for suitable ISOs and for some reason it checks any ISO it finds in the root of partitions. In this case it's trying to look in NFSUG2_DISK2.iso and failing. If you just move that (and any other ISO's) from the root of E:\ into a subfolder it should work okay.
