What am I seeing?
I'm not able to install Windows 7* or Windows* Server 2008 R2.
Why am I seeing it?
The reason why this problem has been occurring is because neither of these operating systems has USB 3.0 drivers embedded in their installation. So you need to add these drivers manually to the .ISO image.
