Hi there, I succesfully installed Windows 8.1 via Bootcamp on my macbook pro (late 2011) in the past. Now I want a clean install and re-install windows. I have windows on disk and the latest support software on a USB drive. Is it possible to: - Insert the Windows installation disk, start the installation (boot/alt), select/format the (already existing) bootcamp partition during installation and install Apple's Support software from drive when finished? Or do I need to: - Start Bootcamp Assistent, delete Windows and its partition and start all over? I actually prefer the first option because the partition is already in place with the right amount of space, but I don't want to mess it up. Any advice? Thanks in advance!
