Well, there are 6 different options to choose from, refresh, load driver, extend, delete, format, and new. I can only click on refresh, load driver, and new.
You're at the screen where it tells you to pick a hard drive to install Windows right? You have to create a partition from the unpartitioned hard drives first, in order to format it. So you have to press C, to create the partition. Type in the size of the partition that you want (30GB is good). And continue.
Ah, why didn't you say so. No wonder. They have a different procedure.
So at the screen where you see refresh, load, and new. Click new, and then set the size of the partition you want to install Vista on, then click Next.
