无法在Ubuntu 15.10上安装USB

我试图按照以下博客文章中的说明创建可启动的Windows 7 USB记忆棒：

• 从LINUX创建可启动的WINDOWS 7 USB驱动器（在UBUNTU上测试）

但是在尝试将/dev/sdb分区从GParted格式化为ntfs后，我无法显示USB。我拔出并重新插入USB。下面是GParted当前显示的内容：

我尝试使用tail -f /var/log/syslog，然后插入USB。以下是输出：

我使用lsblk了以下输出：

sdb在这里可见。它也显示在GParted中。但是它没有显示在“文件”窗口中。

我尝试/dev/sdb1使用进行安装mount /dev/sdb1 /mnt，然后运行sudo mount并获得以下输出：

/dev/sdb1 on /mnt type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)

USB仍未显示在“文件”中。

请帮我。
