Hey, I got myself in a situation where I've got Win 7 on Bootcamp version 4.0.4033. It works fine however there are some issues with a PCI card and SSD Boot volume that I have heard has to do with Win 7. I am trying to determine how to move forward here. I would like to install 8,1 or 10 but am unclear which version of Bootcamp I should try to download. There is information scattered all over the place. I came across this link which seems somewhat promising...
