Is this possible.?? Here is what i did:
>Downloaded wubi from here :http://releases.ubuntu.com/natty/
(because i have an ISO as Pinguy_OS_11.04.1_x86-64 )
>Disconnected from internet
>Placed both the wubi and ISO in same folder.
But the wubi throws an error on installation. I am selecting "ubuntu" in wubi from the drop down menu.. Check the screenshot below:
