Usually that happens if you're trying to install on a dynamic 'disk'.

With Win7 now it offers to convert to dynamic disks when you already have 4 primary partitions and you try to create another. Unfortunately this process is not easily reversible and these partitions are not visible to linux as they're not in the MBR partition table.

In fact that error is not Wubi, it's Windows preventing you from booting directly from the dynamic partition. It would work if you picked C: but don't do this - running linux on a disk with dynamic partitions can lead to data loss (since they're not visible to Ubuntu).

Here's a thread where the poster converted from dynamic back to simple: http://ubuntuforums.org/showthread.php?t=1868679
