Start-up Selection Issue

Hello,

I've been having a problem, I recently recovered an old hard drive on my computer.

Now, whenever I startup my computer, about 5 seconds later I am given with a screen with the 2 harddrives (Or whatever they are called) options saying
"Microsoft Windows Vista"
And I can't quite remember the other ones name but it was about
"Microsoft windows Vista (Recovered)"

Now, after a few seconds it automatically selects the first one (Being Microsoft Windows Vista) and that is the drive I don't want. I want the Microsoft windows Vista (Recovered) drive.
Is there some way I can make it automatically select the Microsoft windows Vista (Recovered) drive without having to go through selecting it?
I want the convenience of not having to wait and select it every time I start my computer.

So is this possible?

Hi,

There are a couple of questions first: -

1. Are there two versions of Vista installed on this drive?
2. What does the "recovered" comment refer to?
