It may be the way you have your partitions set up, I really didn't understand what you were trying to do with those other partitions, it was a confusing diagram, atleast to me
You could just do two partitions. Make 2 HFS+ partitions, name one Mac OS 9 and the other Mac OS X, size them however you'd like, and then install from there. This may fix that error. I haven't tried it, so I'm not sure.
