How do I install boot manager?

How can I install boot-manager to ubuntu 12.04? I have tried sudo apt-get install boot-manager but it does not work.

Why I want is because I will close some startup application in order to optimize system performance.

EDIT:

E: Unable to locate package boot-manager

Running these commands in a Terminal window (Ctrl+Alt+T) should do it for you:

sudo apt-get update
sudo apt-get install bum

When trying to find a package like that, it helps to use the Synaptic Package Manager. When I searched 'boot-manager' in it, the 'bum' package came up.

sudo apt-get install bum 

try to use this command.
