Could not install the CP to a defined partition

I wanted to install the CP to a partition I defined on my eSata drive. But it never gave me any option to select a partition. It just installed it into my Win7 C partition. Fortunately I had anticipated trouble and had made a Win7 image before I tried to install the CP. Now I got rid of the bugger and wonder how I get it to install in a double boot.

Beta-fish doesnt like some dual boot installs. Took several attempts (and an image) just to get it working. Ugh!
