Is D: a dynamic disk? I believe that windows allows more than 4 primary partitions using dynamic disks but these cannot be used for Ubuntu since they're managed by windows. Since wubi doesn't need a separate partition (or get any benefit from running on a separate partition) I'd just use C:.

Note: in fact there is a known bug that occurs when running wubi on a separate partition to windows - whenever you upgrade package grub-pc you can leave your wubi install unbootable or damage your bootloader as it doesn't recognize wubi installs unless they are on the same partition as windows.

Could not solve this problem....
So downloaded the iso and used a usb instead...Surprisingly that did not create any problem installing in another drive...
