Mouse/Keyboard won't work during installation of Windows 7 during Bootcamp.

Mouse/Keyboard won't work during installation of Windows 7 during Bootcamp. Could some one help me?

I tried to install windows 7 through the Bootcamp Assistent, finally it worked. And then i restart my mac to windows 7 screen, then i see the install home screen of windows 7.

(this picture is just from the internet, you see here the cursor of the mouse, i don't have that)

But i can’t do anything because my mouse and keyboard won’t worked ( i don't have a mac mouse or keyboard, is just normal keyboard and mouse). Seems i need to install mouse drive and keyboard drive. But how do i do this? I can't do anything in the windows 7 screen.

Help?

Thanks
