How to Install Windows 10 on a New PC

Building a new PC is an exciting endeavor, and the final, crucial step to bringing your custom rig to life is installing the operating system. Windows 10 remains a dominant force in the desktop OS market, offering a stable, feature-rich, and widely compatible platform for gaming, productivity, and everyday use. This guide will walk you through the entire process of installing Windows 10 on your brand-new machine, from preparing your installation media to the final system configurations.

Preparing Your Windows 10 Installation Media

Before you can install Windows 10, you’ll need a bootable USB drive or DVD containing the installation files. The most common and recommended method today is using a USB drive, as it’s faster and more widely supported by modern motherboards.

Downloading the Windows 10 Media Creation Tool

The official and safest way to obtain the Windows 10 installation files is through Microsoft’s Media Creation Tool.

1. Visit the Microsoft Download Page: Navigate to the official Windows 10 download page on Microsoft’s website. Search for “Download Windows 10” in your preferred search engine, and ensure you are on a legitimate Microsoft domain.
2. Download the Tool: Look for the “Download tool now” button under the “Create Windows 10 installation media” section. Save the executable file to a convenient location on a working computer.
3. Run the Media Creation Tool: Once downloaded, double-click the executable file to launch the tool. You will need to accept the license terms.
4. Select “Create installation media (USB flash drive, DVD, or ISO file) for another PC” and click “Next”.
5. Choose Language, Edition, and Architecture: The tool will likely default to recommended options for the PC it’s running on. To install on a new PC, uncheck “Use the recommended options for this PC” and select your desired language (e.g., English), edition (Windows 10 Home or Pro – ensure this matches your intended license), and architecture (64-bit is standard for modern PCs). Click “Next”.
6. Select “USB flash drive”: Choose this option to create a bootable USB. Ensure you have a USB drive with at least 8GB of storage. Warning: All data on the USB drive will be erased during this process, so back up anything important.
7. Choose Your USB Drive: Select the correct USB drive from the list of available removable drives. If your drive isn’t listed, ensure it’s properly connected and try clicking “Refresh drive list”. Click “Next”.
8. Downloading and Creating Media: The tool will now download the Windows 10 installation files and create the bootable USB drive. This process can take a significant amount of time, depending on your internet connection speed. Once complete, you will see a message indicating the USB flash drive is ready. Click “Finish”.

Alternative: Creating an ISO File

If you prefer to create an ISO file (which can then be burned to a DVD or used with virtual machine software), you can select “ISO file” in step 6 of the Media Creation Tool process. This will save an ISO image to your computer, which you can later burn to a DVD using Windows’ built-in disc image burner or tools like Rufus for more advanced bootable media creation.

Configuring Your PC’s BIOS/UEFI for Booting

Your new PC’s motherboard needs to be instructed to boot from the USB drive (or DVD) you’ve prepared. This is done through the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) settings.

Accessing BIOS/UEFI

1. Insert Bootable Media: Connect your prepared Windows 10 USB drive to a USB port on your new PC, or insert the Windows 10 DVD into the optical drive.
2. Power On Your PC: Turn on your new computer.
3. Press the BIOS/UEFI Key: Immediately after powering on, you’ll need to press a specific key repeatedly to enter the BIOS/UEFI setup utility. The most common keys are DEL (Delete), F2, F10, F12, or ESC. The exact key is usually displayed on the initial boot screen (e.g., “Press DEL to enter Setup”). If you miss it, simply restart your PC and try again.
4. Navigate the BIOS/UEFI Interface: The interface varies between motherboard manufacturers, but generally, you’ll use the arrow keys to navigate and Enter to select. Look for an option related to “Boot,” “Boot Order,” “Boot Priority,” or “Boot Sequence.”

Setting the Boot Order

Within the Boot settings, you need to prioritize your USB drive (or DVD drive) over your internal hard drive or SSD.

1. Locate Boot Options: Find the section that lists the boot devices. It might be labeled “Boot Device Priority,” “First Boot Device,” “Second Boot Device,” etc.
2. Prioritize USB/DVD: Select your USB flash drive (it might be listed by its manufacturer name or as “USB HDD” or “Removable Device”) or your DVD drive as the “First Boot Device.”
3. Save and Exit: Navigate to the “Exit” or “Save & Exit” section. Select “Save Changes and Exit” (often mapped to F10). Your PC will restart.

If you’ve correctly configured the boot order, your PC should now boot from the Windows 10 installation media. You’ll see a prompt like “Press any key to boot from USB…” – if so, press any key immediately.

Installing Windows 10: Step-by-Step

Once your PC boots from the installation media, the Windows 10 setup process will begin.

Initial Setup Screens

1. Language, Time, and Keyboard: The first screen will prompt you to select your language, time and currency format, and keyboard input method. Choose the appropriate options and click “Next.”
2. Install Now: Click the prominent “Install now” button.
3. Product Key: You will be asked to enter your Windows 10 product key.
   • If you have a key: Enter it accurately.
   • If you don’t have a key yet: Click “I don’t have a product key.” You can activate Windows later after installation. This is common for new builds where you might purchase a key later.
4. Select Operating System Edition: If you skipped the product key, you’ll be prompted to choose the edition of Windows 10 you want to install (e.g., Windows 10 Home, Windows 10 Pro). Make sure this choice aligns with the license you intend to use.
5. Accept License Terms: Read and accept the Microsoft license terms by checking the box and clicking “Next.”
6. Choose Installation Type: You will be presented with two options:
   • Upgrade: This option is for upgrading an existing Windows installation to a newer version, keeping your files, settings, and applications. This is NOT suitable for a new PC.
   • Custom: Install Windows only (advanced): Select this option for a clean installation on your new hardware.

Drive Partitioning and Formatting

This is a critical step for a new PC, as you’ll be designating where Windows will be installed.

1. Select Drive: You will see a list of drives and partitions on your system. For a new PC with unallocated space, you will see your SSD or HDD listed as “Drive X Unallocated Space.”
2. Create Partitions (Optional but Recommended):
   • Single Partition: The simplest approach is to select the unallocated space and click “Next.” Windows will automatically create the necessary partitions (System Reserved, Recovery, and the main OS partition).
   • Multiple Partitions: If you want to manually create partitions (e.g., a separate drive for your OS and another for your data), select the unallocated space, click “New,” enter the desired size in MB (1024 MB = 1 GB), and click “Apply.” Windows will still create its system partitions. Repeat this for any additional partitions you wish to create.
3. Choose Primary Partition: Select the partition where you want to install Windows (usually the largest one you created or the unallocated space if you’re letting Windows handle it) and click “Next.”
   • Formatting (if applicable): If you are installing on a drive that has been previously used or if you created multiple partitions, you might see an option to “Format” a selected partition. Formatting erases all data on that partition. For a clean install on a new, unformatted drive, this step is usually handled automatically when you click “Next.”
4. Installing Windows: The setup will now begin copying files, installing features, and performing updates. Your PC will restart several times during this process. Important: After the first restart, your PC might try to boot from the USB drive again. If it does, you may need to remove the USB drive or quickly enter BIOS/UEFI again and change the boot order back to your hard drive/SSD, or simply let it boot from the drive and it will continue the setup without the USB.

Out-of-Box Experience (OOBE) and Initial Setup

After the core installation is complete and your PC has restarted a few times, you’ll be guided through the Out-of-Box Experience (OOBE) to set up your user account and personalize Windows 10.

Region and Keyboard Layout

1. Select Your Region: Choose your country or region.
2. Select Keyboard Layout: Confirm or choose your keyboard layout. You can add a second keyboard layout if needed.

Network Connection

1. Connect to a Network: Windows 10 will typically prompt you to connect to a network (Wi-Fi or Ethernet). For a new build, ensure your Ethernet cable is connected or that you have your Wi-Fi credentials ready. Connecting to the internet at this stage allows Windows to download updates and drivers during setup.
2. Drivers: If your network adapter drivers are not yet installed or recognized by Windows, you might not be able to connect. In this case, you might need to skip this step, install essential drivers manually (e.g., from your motherboard’s support website via another PC and a USB drive), and then reconnect.

Account Setup

1. Microsoft Account vs. Local Account: You’ll be given the choice to sign in with a Microsoft account or create a local account.
   • Microsoft Account: This offers seamless syncing of settings, OneDrive integration, and access to the Microsoft Store.
   • Local Account: This creates a standard user account tied only to your PC, without cloud integration. For a new PC, if you haven’t purchased your Windows license yet and are using the “I don’t have a product key” option, you might be pushed towards a Microsoft account. You can often find an option to “Offline account” or “Skip this step” to create a local account, sometimes hidden under less obvious links.
2. Create Your Account: Follow the prompts to create your username and password (and security questions for a local account).
3. PIN Creation: You’ll likely be prompted to create a PIN for faster login.

Privacy Settings

1. Review Privacy Options: Windows 10 will present a series of privacy settings, including location services, diagnostic data, tailored experiences, and advertising ID. Review each option carefully and enable or disable them according to your preferences. It’s recommended to disable options you’re not comfortable with.

Cortana and Other Features

1. Cortana Setup: You may be asked if you want to set up Cortana, Microsoft’s virtual assistant. You can choose to enable or disable it.
2. Finalizing Settings: Windows will apply your chosen settings and finalize the installation. This may involve another restart.

Post-Installation Steps and Driver Installation

Once you reach the Windows 10 desktop, your PC is technically installed and usable. However, to ensure optimal performance, stability, and functionality, several post-installation steps are crucial.

Install Essential Drivers

Drivers are software that allows Windows to communicate with your hardware. Without the correct drivers, your hardware might not function properly, or at all.

1. Motherboard Drivers:
   • Chipset Drivers: These are usually the most critical. They manage communication between your CPU, RAM, and other components.
   • Audio Drivers: For sound output.
   • LAN (Ethernet) Drivers: If not already installed.
   • Wi-Fi/Bluetooth Drivers: If applicable.
   • USB Drivers: To ensure all USB ports function correctly.
   • SATA/NVMe Drivers: For storage devices.
   • How to install: Visit your motherboard manufacturer’s website (e.g., ASUS, Gigabyte, MSI, ASRock), find the support page for your specific motherboard model, and download the latest drivers for Windows 10 (64-bit). Install them one by one, often starting with chipset drivers.
2. Graphics Card Drivers:
   • If you have a dedicated GPU (NVIDIA or AMD), download the latest drivers directly from the manufacturer’s website (NVIDIA GeForce or AMD Radeon). These are essential for display output, performance in games, and video rendering.
3. Other Peripherals: Install drivers for any other hardware you’ve connected, such as printers, scanners, or specialized input devices.

Run Windows Update

Even after the initial installation, Windows Update is vital for security patches, bug fixes, and sometimes even driver updates.

1. Access Windows Update: Go to Settings > Update & Security > Windows Update.
2. Check for Updates: Click “Check for updates.” Let Windows download and install all available updates. This process can take time and may require multiple restarts.

Activate Windows

If you skipped product key entry during installation, it’s time to activate your copy of Windows 10.

1. Go to Activation Settings: Navigate to Settings > Update & Security > Activation.
2. Enter Product Key: Click “Change product key” and enter your valid Windows 10 product key.
3. Troubleshoot: If you encounter issues, use the activation troubleshooter or contact Microsoft support.

Install Essential Software

With Windows installed and drivers updated, you can begin installing your preferred applications.

• Web Browsers: Chrome, Firefox, Edge.
• Productivity Suites: Microsoft Office, LibreOffice.
• Media Players: VLC Media Player.
• Communication Tools: Discord, Skype, Zoom.
• Antivirus Software: If you don’t rely solely on Windows Defender.
• Gaming Platforms: Steam, Epic Games Store, etc.

Create a System Restore Point

Once your system is stable and configured, it’s a good practice to create a system restore point. This allows you to revert your system to a previous state if something goes wrong in the future.

1. Search for “Create a restore point” in the Windows search bar and open it.
2. Click “Create…” under the “Protection Settings” for your system drive. Follow the prompts to name and save the restore point.

By following these steps, you’ll have successfully installed Windows 10 on your new PC, ready to be customized and used to its full potential. Enjoy your new build!
