Can I simple format the macbook pro HD and install windows 7 then use the bootcamp drivers inside the macos dvd? Does Windows 7 installation in a mac use the same drivers as a standard PC (I mean nvidia geforce drivers, audio drivers, etc)?
Yes, yes it does. However, it is more advisable to run the bootcamp assistant from within Mac OSx first to get the drivers. The reason being that the drivers the unit shipped with are not likely the most current/stable drivers. In several models of MacBooks, the original drivers available had conflicts with other software/windows processes.
You access bootcamp assistant from the Applications/Tools menu in Mac OSx. From there, it will let you copy all the most up to date drivers to a USB flash drive for after you install Windows 7.
I hope this helps you.
