Your MBP does not support installing Windows from a USB. You will need to use the built-in optical drive and a physical DVD. The following is the list of the 2011/2012 Macs that support USB installation of Windows. 2013 and later models without Optical drives will support USB booting.
Do not modify Bootcamp info.plist to enable this option, because it will cause problems later.
