Start ImageX Tool

ImageX is a command-line tool used to capture, Edit and export an operating system installation image to a Windows Imaging Format (WIM) file.

  1. Download ImageX.
  2. Run Command Promp as Administrator and go to the directory in which ImageX.exe is located (makes it simple by moving it to root directory ( in my example C:\imagex.exe ).Install Multiple Windows

Note: If your Windows ISO or DVD has multiple Windows images for several Windows versions like Windows 7 Home Basic, Ultimate, Enterprise, etc.,

So, you have to know the Index for the correct Windows version you want to install. To do this, Type this command in Command Prompt:

dism /Get-WimInfo /WimFile:F:\sources\install.wim
Install Multiple Windows

Install Windows to VHD

In the command prompt, Type the following command:

imagex.exe /apply E:\sources\install.wim 4 F:\

This command essentially means: install ( Apply ) Windows 7 from the install.wim file located in the sources directory which is ( F:\sources ) and selecting the 4th OS instance ( 4 ) in the WIM file which is Ultimate Edition and installing it to drive ( E:\ ) which is the attached VHD.
Install Multiple Windows

Add The New Installation to Boot Menu

Once the process is completed, You need to add the new installation which located now on the VHD file ( Drive F:\ ) to Boot Menu, so you can choose it to boot after restarting your PC.
Use the following command in Administrative Command Prompt to add the installation to Boot Menu:

bcdboot E:\windows
Install Multiple Windows

When you boot to the new installation for the first time, Windows will detect your devices and install the appropriate drivers and then will reboot again.

Upon reboot, you will asked to configure Language, time and currency format, user account, computer name, etc,. just like a normal windows installation.Multiboot Windows

Now, You have an additional windows 7 on your PC.

Windows 8.1 & Windows 10 Installation

You can use the same steps to install another windows 10 or 8.1, Just convert the install.esd to install.wim to be able to use ImageX tool.

Also, You can perform the same process of ImageX to install Additional Windows to another Partition on your Hard Drive instead of the Virtual Hard Drive (VHD).
