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
- 1 Prerequisite
- 2 Step 1: Integrate the USB 3.1 Drivers into the USB Key
- 3 Step 2: Install Windows 7 on a PC with USB 3.1
- 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.
Step 1: Integrate the USB 3.1 Drivers into the USB Key
- Open the command prompt as admin.
- 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
- Create a Windows 7 installation USB key from the downloaded ISO and identify the drive letter assigned to the USB key (eg F ).
- 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 .
- 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).
- 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
- 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
- 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
