Vista recover

[juhu]

I recovered Vista OS with recovery dvd and got stuck in a problem. Before recovering, I had 150 GB on 1st partition with VistaOS and about 300 GB on another partition for data storage. But now, partition sizes changed. On VistaOS partition I have about 250 GB ( I don't need so much for OS) and 200 Gb on another for data ( not enough ).

As I can remember, while recovering I got a popup menu with 4 options like : recover Vista on one partition, recover on both partitions, recover on all hdd...etc. I checked this "recover on all hdd", so I got unwanted partition sizes. How can I reduce my own partition sizes during recovery ? Which option should I choose ? Or there's another alternative ?
