Need help: Sony SZ670, wanted to have Leopard/vista dual boot

[coolfire74]

Hi, I am newbie here. I am planning to install the leopard on my sony SZ670 (with vista already installed). But before I start this project, I would like to ask you guys some questions. Any suggestions will be highly appreciated.

 

1). Which version would work best on sony SZ, with everything functional? Could you guys give me the name of that disk iso, so that I can download it? Where I can find the instructions? Believe me, I did search before asking, and I have read some already. But it was really hard to find a method adapted to sony SZ series. Thanks!

 

2). I have vista installed on drive C, and I have already make a logical drive D for leopard, and moved all my work and impoart data to drive E and made backups on external hard drive already. My question is, after leopard installation, I guess I can not boot into vista in C drive anymore. How can I make the vista come back? How can I make the dual boot? Which software should I get? Could you please give me some suggestion?
