Step-by-Step Guide

Step 1: Prepare Your System

Before beginning the installation process, ensure your computer meets the minimum hardware requirements for the Windows version you intend to install. Typically, these requirements include:

• Processor: 1 GHz or faster compatible processor
• RAM: Minimum 2 GB for 64-bit or 1 GB for 32-bit Windows
• Storage: At least 20 GB free space
• Graphics: DirectX 9 or later with WDDM 1.0 driver
• Display: 800x600 resolution or higher

Additionally, back up all important data. Installing Windows often involves formatting your hard drive, which deletes existing data.

Step 2: Create a Bootable Installation Media

To install Windows, you need a bootable USB drive or DVD containing the Windows installation files. Follow these steps:

1. Download the official Windows ISO file from Microsoft’s website.
2. Use a tool like Rufus or the official Windows Media Creation Tool to create a bootable USB drive.
3. Insert a USB flash drive with at least 8GB capacity into your computer.
4. Run the chosen tool, select the ISO file, and choose the USB drive as the destination.
5. Start the process and wait until the tool finishes creating the bootable media.

Step 3: Configure BIOS/UEFI Settings

To boot from the installation media, you must configure your computer’s BIOS or UEFI settings:

1. Restart your computer and press the key to enter BIOS/UEFI (often F2, Delete, or Esc).
2. Navigate to the Boot menu.
3. Set your USB drive or DVD as the primary boot device.
4. Save changes and exit BIOS/UEFI.

Step 4: Start the Windows Installation Process

With the bootable media inserted, restart your computer. The system should boot into the Windows Setup environment:

1. Select your language, time, and keyboard preferences.
2. Click Install Now.
3. Enter your Windows product key if prompted, or click I don’t have a product key to activate later.
4. Choose the Windows edition you want to install.
5. Accept the license terms and click Next.

Step 5: Choose Installation Type

You will be given two options:

• Upgrade: Keeps your files, settings, and applications (only available if upgrading from a previous Windows version).
• Custom (Advanced): Performs a clean installation.

For new setups or troubleshooting, select Custom.

Step 6: Partition Your Hard Drive

In the next screen, you will see your available drives and partitions:

• Delete existing partitions to create unallocated space for a clean install (make sure data is backed up).
• Create a new partition in the unallocated space for Windows installation.
• Select the partition and click Next to continue.

Step 7: Installation and Setup

Windows will now copy files, install features, and configure settings automatically. This process may take 20 to 40 minutes depending on hardware speed.

After installation, the system will reboot several times. Do not remove the installation media until you reach the initial Windows setup screens.

Step 8: Configure Windows Settings

Once installation is complete, you will be guided through initial setup:

• Select region and keyboard layout.
• Connect to a Wi-Fi network.
• Create or sign in with a Microsoft account.
• Configure privacy settings.
• Set up a PIN for quicker login.

Step 9: Install Drivers and Updates

To ensure hardware functions optimally, install the latest drivers:

• Open Device Manager to check for missing drivers.
• Download drivers from your computer manufacturer’s website.
• Run Windows Update to apply system and security updates.
