Okay i read that if you are running Backtrack 4 on vmplayer as a guest operating system it doesn't detect your internal wireless card as a physical device and will not show up when you type in airmon-ng. I read it only detects usb devices. Is that true? I am running windows 7 and am wondering if i could mess up my operating system by installing backtrack 4 on my hard drive? also if i do install it on my hard drive will my internal wireless card work with airmon-ng? Thanks
