Installing “Windows 11” using the “Command Prompt (CMD)” may sound technical, but it is a powerful and reliable method when the standard graphical installer fails or is unavailable. This approach is especially useful for troubleshooting corrupted systems, performing clean installations, or working in recovery environments where the graphical interface cannot load. By using CMD, you gain direct control over disk partitioning, formatting, and installation execution.
This guide walks you through the complete process in clear language. You will learn how to prepare your system, use essential commands, and complete a successful installation step by step.
Do these Before Installing Windows 11 Via CMD
Installing an operating system modifies your storage drive significantly, so taking a structured approach ensures success.
First, ensure your system meets the “Windows 11 system requirements”, including TPM 2.0, Secure Boot capability, at least 4 GB RAM, and 64 GB storage. While CMD installation can bypass some checks, it is still recommended to meet official requirements for stability.
Next, create a “bootable USB drive” containing the Windows 11 installation files. You can use tools like the Media Creation Tool or manually copy the ISO contents to a formatted USB drive. The USB must be set up correctly because CMD will rely on these files during installation.
Back up all important data from your computer. The installation process may involve formatting your drive, which permanently deletes existing files. Store backups on an external drive or cloud storage.
You should also access your system’s “BIOS or UEFI settings” and configure the boot order, so the computer starts from the USB drive. This is essential because the CMD installation begins from the bootable media environment.
Finally, keep a stable power supply and avoid interruptions. Any disruption during installation can corrupt the system and require starting over.
How to Install Windows 11 Using CMD?
To install “Windows 11 using CMD”, boot your computer from a Windows 11 USB drive, open Command Prompt using Shift + F10, use Diskpart to format the drive, and then run the setup.exe command from the installation files to begin the installation process. Follow on-screen instructions to complete the setup.
Step 1: Boot Your Computer Using Installation Media
The first step is to start your computer using the prepared “bootable USB drive”. Insert the USB into your system and restart the computer. As the system begins to power on, press the appropriate key, such as F2, F12, DEL, or ESC, to open the boot menu.
Select the USB device from the list of boot options. Once selected, your system will load the Windows setup environment. This environment is often referred to as the “Windows Preinstallation Environment”, which allows you to perform system-level tasks before the operating system is installed.
When the Windows Setup screen appears, do not proceed with the normal installation. Instead, you will open CMD to control the process manually.
Step 2: Open Command Prompt in Setup Environment
Once you are on the Windows Setup screen, press “Shift + F10” on your keyboard. This keyboard shortcut launches the “Command Prompt” window instantly.
CMD is a text-based interface where you type commands to perform operations. It may look intimidating at first, but each command you will use is simple and structured.
This environment gives you full administrative access to your system’s storage and installation files. You will use it to prepare your disk and initiate the installation manually.
Step 3: Launch Disk Partition Tool Using Diskpart
In the Command Prompt window, type “diskpart” and press Enter. This opens the “Disk Partition Utility”, which is used to manage drives and partitions.
Diskpart is a powerful tool, so accuracy is important. Once inside, type “list disk” and press Enter. This command displays all available storage drives connected to your system.
Identify your primary disk, usually labeled as Disk 0. Then type “select disk 0” and press Enter to choose it. Make sure you select the correct disk, as the next steps will erase data.
Step 4: Clean and Format the Drive
After selecting the correct disk, type “clean” and press Enter. This command removes all existing partitions and data from the drive, effectively resetting it.
Next, create a new partition by typing “create partition primary” and pressing Enter. Once created, select it using “select partition 1”.
Now format the partition using the command “format fs=ntfs quick”. This prepares the drive using the NTFS file system, which is required for Windows installation.
Finally, assign a letter to the partition by typing “assign letter=C”. This step ensures the system recognizes the drive during installation.
Step 5: Exit Diskpart and Locate Installation Files
After formatting is complete, type “exit” to leave Diskpart. You will return to the main Command Prompt window.
Now, you need to locate the USB drive containing the Windows 11 files. Type “diskpart” again, then use “list volume” to view all volumes and their assigned letters.
Identify your USB drive, which is usually labeled with a different letter, such as D or E. Type “exit” again to return to CMD.
In Command Prompt, switch to the USB drive by typing its letter followed by a colon. For example, type “D:” and press Enter.
Then type “dir” to view the contents. You should see files like setup.exe, the sources folder, and boot files. These are required for installation.
This step confirms that you are in the correct directory before running the installation command.
Step 7: Run the Windows Setup Command
To begin the installation, type “setup.exe” and press Enter. This command launches the Windows 11 installation process manually.
The graphical installer will now appear. From here, you can follow the standard setup steps such as selecting language, region, and keyboard layout.
Choose the partition you created earlier when prompted. The installer will copy files, install features, and configure settings automatically.
Step 8: Complete the Installation Process
After the installation begins, your system will restart multiple times. Do not interrupt the process. Each restart continues the setup until the system is fully installed.
You will eventually reach the “Out of the Box Experience”, where you configure user settings, create an account, and personalize your system.
Follow the on-screen instructions carefully. Once completed, your Windows 11 system will be ready to use.
Things to Do Post Installation
After installation, it is important to perform a few essential tasks. First, install the latest “Windows updates” to ensure your system is secure and optimized. Updates often include security patches and performance improvements.
Next, install device drivers for graphics, audio, and network components. While Windows installs basic drivers, manufacturer-specific drivers provide better performance.
You should also install essential software such as browsers, antivirus programs, and productivity tools. Restoring your backed-up data is another important step.
Finally, activate Windows using a valid product key to unlock full functionality.
Extra Tips
When using CMD, always double-check commands before pressing Enter. Incorrect commands can lead to data loss or installation failure.
Keep your USB drive in good condition and avoid removing it during installation. A corrupted installation file can cause errors.
If you encounter compatibility issues, consider enabling or disabling Secure Boot in BIOS settings depending on your system configuration.
It is also helpful to understand basic CMD navigation commands like “cd”, “dir”, and “exit” to move through directories efficiently.
