There are two simple ways to solve the problem. The first way is to use the Windows 7 USB/DVD Download Tool, the distribution of which can be downloaded from the official website on the following link
After installing the program, you need to check two packages in your system: Microsoft .NET Framework 2.0 and Microsoft Image Mastering API. If they are missing, download them from the official website of the developer (Microsoft).
Run the program and click the Browse button next to Source File to specify the path to the installation image in iso format. Then click the Next button.
In the next window you must specify the type of media that you will use. Here you will find 2 options: DVD and USB. At this point you must press the USB button.
Then from the list select the flash media that will be used (if several). To proceed to the next step, click Begin copying".

In the empty field "Path to file" Windows, you must specify the path to the files of the mounted image. And in the "USB disk", specify the path to the flash drive. To start creating the bootable media, click "Start".
