Can I use NVDA portable to install Windows 7 from scratch?

Greetings to all,
I wonder if I can use NVDA that is on a bootable Windows PE to install Windows 7?
If not, can I do this with the Narrator that comes with Windows 7?  If so, what keystrokes start up Narrator in 7?
Any and all suggestions and steps will be greatly appreciated.
