Installed Vista on wrong partition

[the DRIZZLE]

When I installed vista I partitioned my 640 gb drive into a 100 and a 500. I wanted vista to install on the 100. I just realized that vista and everything else is installed on teh 500gb partition. Vista will only let me shrink it down to 320gb. How can I fix this?

edit:

This is wierd but vista lists the 100 bg partition as the d: and says its the primary. Maybe I can ghost everything on the smaller partition?

You might try this program:

Acronis Disk Director Suite 10 did the trick (only the 260 build is Vista-compatible)
