Hi:
Before I could install Fedora I had to shrink my Win's 7 partition first.
I shrunk the Windows partition to about 1/2 it's size.
When it came time to partitions and write to disk:
I manually created the necessary partitions for the Fedora install and the installation was successful.

You could use a LIVE version of G-parted to manipulate all of the partitions that you currently have but that's up to you. I prefer to use what the Fedora installer and partition manager offers.
