Install Windows 7 on a PC with USB 3.1 ports 2018

You can not install Windows 7 on your computer with this damn USB key to install Windows 7? The problem is surely in the absence of the USB 3.1 driver! ☝Indeed, the ISO of Windows 7 does not include USB 3.1 drivers which are however necessary for the installation of Windows 7 on PCs equipped only with USB 3.1 ports (no USB 2.0 ports and no CD / DVD player ).

During the installation of Windows 7, you most certainly have the following error message :

A CD / DVD drive driver is missing. If you have a floppy disk, CD, DVD, or USB flash drive that contains the driver, insert it now.

Note: If the Windows installation media is in the CD / DVD drive, you can safely remove it for this step.

To work around this message and install Windows 7 on your computer, it is necessary to copy the USB 3.1 controller driver from your computer to the Windows 7 installation USB key.

It is a bit complicated but do not worry: following this tutorial, everything will be fine and Windows 7 will eventually be installed on your PC

Note: USB 3.0, the third major release of Universal Serial Bus (USB), has been renamed USB 3.1 Gen 1 by the USB Implementers Forum (USB-IF). So if you were wondering: USB 3.0 = USB 3.1 Gen 1 !?

  • In the UEFI firmware settings :
    • have disabled the Secure Boot ;
    • have enabled the Compatibility Support Module ( CSM ), also known as Legacy Boot Mode.
  • The ISO of Windows 7
  • The USB controller driver of the computer.

    The USB controller driver

    The vast majority of your computer uses the motherboard chipset USB controller, but it can also use a third-party chip (such as ASMedia) if it has one. To be clear, consult the documentation on the motherboard or PC, or use the HWiNFO software . It is important to use the controller driver that manages the USB port that you will use to install Windows 7.☝

    Once the USB controller is identified, download its driver either from the website of the manufacturer of the motherboard or from the computer (HP, Asus, Lenovo …) or on the websites of Intel and AMD (if the USB ports are managed by the chipset):

    • USB 3.1 driver for Intel series 7 chipsets ;
    • USB 3.1 driver for Intel 8/9/100 series chipsets ;
    • USB 3.1 driver for AMD series 6/7/8/9 chipsets and AMD AM4 / TR4 sockets .

Step 1: Integrate the USB 3.1 Drivers into the USB Key

  1. Open the command prompt as admin.
  2. Create two mount and usb3 folders in a win7usb3 folder in the user’s Temp directory :
    cd %temp%
    mkdir win7usb3
    cd win7usb3
    mkdir mount && mkdir usb3
  3. Create a Windows 7 installation USB key from the downloaded ISO and identify the drive letter assigned to the USB key (eg F ).
  4. Copy the boot.wim and install.wim files from the USB drive to the win7usb3 folder :
    copy F:\sources\boot.wim . && copy F:\sources\install.wim .
  5. Copy the USB 3.1 driver files to the win7usb3 \ usb3 folder .
    For example, in the Intel-distributed archive, the USB drivers are located in the Drivers \ Win7 \ x86 and x64 folders. Copy only the drivers that correspond to the ISO architecture (32-bit / x86 or 64-bit / x64).
  6. Integrate the USB 3.1 driver into the boot.wim file by entering the following commands:
    DISM /Mount-Wim /WimFile:boot.wim /Index:2 /MountDir:mount
    DISM /Image:mount /Add-Driver:"usb3" /Recurse
    DISM /Unmount-Wim /MountDir:mount /Commit
  7. Do the same for the file install.wim ( replace X with the index of the edition of Windows 7 to install, see below):
    DISM /Mount-Wim /WimFile:install.wim /Index:X /MountDir:mount
    DISM /Image:mount /Add-Driver:"usb3" /Recurse
    DISM /Unmount-Wim /MountDir:mount /Commit

    Indexes and editions of Windows 7

    The install.wim file can contain multiple editions of Windows 7identified by indexes :

    • index 1: Windows 7 Home Basic;
    • index 2: Windows 7 Home Premium;
    • index 3: Windows 7 Professional;
    • index 4: Windows 7 Ultimate.

    You must update the index of the edition of Windows 7 that you want to install. For example for Windows 7 Professional:

    DISM /Mount-Wim /WimFile:install.wim /Index:3 /MountDir:mount
    DISM /Image:mount /Add-Driver:"usb3" /Recurse
    DISM /Unmount-Wim /MountDir:mount /Commit

    You will find all available indexes in the install.wim file with the command:

    DISM /Get-WimInfo /WimFile:install.wim

    If you want to update all editions of Windows 7, you will need to repeat the above three commands for each index.

  8. Copy the modified boot.wim and install.vim files to the Windows 7 installation USB key:
    copy boot.wim F:\sources\ && copy install.vim F:\sources

That’s it, your Windows 7 USB 3.1 compatible USB stick is ready! Let ‘s move on to installing Windows 7

Step 2: Install Windows 7 on a PC with USB 3.1

  1. Start your PC on the Windows 7 USB 3.1 compatible USB stick, instead of booting to the system disk as usual.
  2. Then follow the instructions of the Windows 7 installer.

Congratulations! You have successfully installed Windows 7 on a PC with USB 3.1 ports !?
