Comment 9 for bug 259540

I have the same problem here, and like Stefano Bragaglia i think that this hidden partition is causing somehow the problem with wubi.
Stefano Bragaglia i dont think that wubi target partition is hardcoded, because before i used windows Vista, and allways installed wubi in D:\ and it's not the first partition.

I think that wubi get somehow the partition number from windows accesible partition.
I mean that for windows 7 the first accessible partition is C:\ and the secon is D:\ etc ...
and when you try to install in D:\ for example, it mark for installation the actual second partition wich in that case is C:\ (because the first is that system reserved), and the files for installation are in D:\, and then BUM -> that error.

My idea and my question here is, is there a way to manualy specify the target partition for the installation process(after reboot).
For now i checked the wubi/grub config files, but didnt found anything to use/change.
