Answer 1

I'm not sure why you're booting DOS from a CD, but won't boot Windows 7 from a CD...

Having said that, Windows Vista and newer no longer use DOS during its initial setup, instead opting to use Windows Preinstallation Environment (PE). There is a much more involved setup, requiring that you create a Windows PE image in advance before you can boot it from the Hard Drive.

Answer 2

You can’t. The install process was completely changed in Vista.

Answer 3

It is not possible to run Vista and Windows 7 installer from command prompt.

when you will try to run it from command mode then it will give error like win32 application will not run in dost mode. (not exactly this).

Windows Preinstallation Environment (PE) may be alternate to do this in dos mode. but according to setup program behavior of windows 7; i do not think it can be achieved easily.. need lots of hard work.

USB Install is much easy with Win2Flash. nice stuff. it is great alternate.
