I've tried to google about this but I can't really get any help regarding this. I thought it'd be better if I could have some advise about this.

Basically, I have to deploy Windows 10 Enterprise to many macbooks (different hdd space).

The problem I'm facing is the fact that each macbook on "El Capitan" will have to download the drivers and then proceed to install Windows 10.

Is there any way which I can bypass the downloading of the bootcamp drivers? Like in the previous OS versions, I'm able to use a dummy USB drive to "bypass" the need for bootcamp driver and then install it manually later.

Does anyone have any suggestion on what I can do?

Is there a tool which I can use to create the partition and also at the same time allows Boot Camp Assistant to recognize it as a Windows partition?
