ok so i can't just put Vista on the other hard drive, I have to make the partition on the new one even if there is nothing on it? how come? Also after I get Vista on the other hard drive how would I pick which OS to go into does it automatically come up when you start up the computer. Sorry for all the questions I just have never done this and I don't wanna miss/mess anything up
You're misunderstanding this. You
can just put Vista on the second hard drive.
You see, a hard drive needs to have a "file system", something that tells the computer how to write and read files from the drive. New hard drives don't come with a built-in file system (we say they disk is
unformatted). In order to use it, you have to make a partition and format that partition with some file system (the standard Windows system is called NTFS). Don't worry about all this technical stuff, the Windows installer does it all for you.
The partition by itself is just a way to give a name to a file system in your hard drive (with letters like C, D, etc). You
can put a single partition in a hard drive, by formatting the whole drive in one go. I know the term sounds like "splitting up", but you can split up a hard drive in only 1 piece.
Hope I'm not confusing you.
As for how to select the OS, you have to install a "boot loader". Every time you turn on the computer, you'll be asked which OS you want to boot into.
I'm not sure, though, if the Vista installer comes with a built-in boot loader. If not, you'd have to use a third party program such as partition magic. I recommend using one to make the partitions in the first place, anyway.
