Obtain the Mac OS X media and you will then be able to proceed.
I am trying to reformat a mac using windows, because the existing installation we do not have the password for. I have tried to both boot a windows xp, and a windows 7 disk, along with a bootable password removal tool all with no luck. It seems that the macbook cannot boot windows discs without first receiving an EFI update.
So i downloaded the EFI update, only to realize it is not a bootable disc (it even says on the mac website that you must run it from within a mac OS).
I need to be able to install windows, but I cant update the firmware, and I don't have a copy of any mac OS's, help!
