Vista start up issue

[Englander]

Today I installed Vista (yay, looks very pretty). The problem is that each time I turn my PC on, it offers me a choice of operating systems to boot:
Vista,
or,
Vista.

Now, this is because I installed it twice, once on a secondary hard drive to check my wireless dongle was compatible and then again on my main hard drive.

What I want to know is how do I make it skip asking me which OS to use during start up? It's a bit annoying to have to press enter everytime I turn on my PC.

Thanks

It's in msconfig, under the boot menu.

Remove the ones you don't need

Go to START
Right click COMPUTER
Click PROPERTIES
Click ADVANCED SYSTEM SETTINGS
Click SETTINGS on Startup and Recovery
