Multi boot with Windows Vista and XP 32/64, boot menu?

I installed windows Vista, along with Windows XP 64 and 32 Bit.

The boot menu shows

Earlier Version of Windows

Windows Vista

and when i choose Earlier Version of Windows it goes to another screen that has windows xp pro, and windows xp x64

How can i make it so that on the Vista Boot Menu, shows all three of them?

I know the answer, but i just wanna make sure.
