I think this is also a duplicate of https://bugs.launchpad.net/ubuntu/+source/lupin/+bug/604417 which is a problem in the lupin overrides of grub, as it relies on the existence of the file /host/wubildr to determine if it's a wubi install. If you don't install wubi on the same partition as windows, then /host/wubildr does not exist, so it assumes it's a real ubuntu install and uses the real grub commands, not the lupin override.
