Hi I downloaded the .iso of windows server standard 2012. I was told to use the windows 7 usb dvd download tool but when I browse to the .iso of windows server standard 2012 and try to load it. It says that "the selected file is not a valid ISO file. Please select a valid ISO file and try again." I cant figure out why it is doing this but is this a common problem? are there alternatives tools that can put windows server 2012 standard onto a bootable USB drive because my server has no dvd drive, just a cd and USBs. Please HHHHHHHEEEEEEEEEELLLLLLLLLPPPPPPPPPPP!!!
