Successfully installing a Windows operating system requires obtaining a legitimate license and preparing the right installation tools. This initial step ensures you have everything necessary for a secure and compliant setup.
To begin, you’ll want to acquire an official Windows license key through authorized channels. Microsoft provides multiple methods for obtaining genuine licenses, including volume licensing verification methods that guarantee authenticity. Consider the following approaches:
- Purchase a license directly from Microsoft’s official website
- Acquire a license through your organization’s volume licensing program
- Buy a license from authorized resellers with documented provenance
A genuine Windows license is your first line of defense against potential security vulnerabilities and system instability.
After securing your license, gather the essential tools for installation:
- Download the official Windows ISO file from Microsoft’s website
- Prepare a USB installation media with at least 8GB capacity
- Download the Windows Media Creation Tool from Microsoft
- Verify the downloaded files match official Microsoft checksums
Professional users should always prioritize purchasing licenses from reputable sources to ensure complete system compatibility and ongoing support. Corporate environments typically use Key Management Service activation for streamlined deployments.
Profi-Tipp: Always keep your license key and purchase documentation in a secure, easily accessible location for future system recoveries or potential technical support inquiries.
Step 2: Create or Prepare Installation Media
Creating a bootable Windows installation USB is a crucial step in preparing for a clean operating system setup. This process allows you to transform a standard USB drive into a powerful installation tool that can boot and install Windows on your computer.
To get started, you’ll need a USB drive with at least 8GB of storage capacity. Microsoft provides multiple methods for creating bootable USB drives that work across different computer systems. Here are the primary approaches:
- Use the official Windows Media Creation Tool
- Utilize third-party tools like Rufus
- Manually create bootable media through command-line interfaces
Ensure your USB drive is formatted and ready before beginning the installation media creation process.
Follow these specific steps to prepare your installation media:
- Download the Windows Media Creation Tool from Microsoft’s official website
- Connect your USB-Laufwerk to your computer
- Run the Media Creation Tool and select your USB as the installation media
- Choose the Windows version and edition you want to install
- Allow the tool to download and write installation files to the USB
Professional users should verify USB compatibility and ensure the drive meets minimum speed and capacity requirements. Some advanced users might prefer alternative bootable USB creation methods depending on their specific system configurations.

Here’s a quick comparison of popular methods for creating Windows installation media:
| Method | Ease of Use | Platform Compatibility | Customization Options |
|---|---|---|---|
| Windows Media Creation Tool | Very user-friendly | Windows only | Limited to official options |
| Rufus (third-party) | Moderately simple | Windows, Linux | Advanced partition settings |
| Manual Command Line | Advanced difficulty | Windows, Linux, macOS | Full custom setup capability |
Profi-Tipp: Always keep your original installation USB in a safe place after creating it, as it can be invaluable for future system repairs or reinstallations.
Step 3: Back Up Data and Configure BIOS Settings
Preparing your computer for a new operating system installation requires careful data preservation and precise hardware configuration. This critical step ensures you protect your existing files and optimize your system’s firmware settings for a smooth Windows installation.
Before making any changes, back up all critical data to an external storage device or cloud service. Configuring BIOS settings systematically involves accessing your computer’s firmware interface and adjusting key parameters. Depending on your computer manufacturer, you’ll access BIOS using different methods:
- Press F2, F10, F12, or Delete during system startup
- Use specific manufacturer key combinations
- Access UEFI settings through advanced Windows startup options
Secure and prepare your system configuration before initiating any major installation process.
Follow these detailed steps for comprehensive system preparation:
- Connect an external hard drive or cloud backup service
- Transfer all important documents, photos, and personal files
- Verify BIOS configuration settings for boot order and security
- Enable Sicherer Start und TPM Einstellungen
- Disable fast startup and hibernation modes
- Set USB or DVD as primary boot device
Professional users should create multiple backup copies and verify data integrity before proceeding. Advanced configurations might require additional systematic BIOS modifications depending on your specific hardware environment.
This reference summarizes common BIOS/UEFI keys by manufacturer for quick access:
| Manufacturer | Common BIOS Key | UEFI/Alternate Key |
|---|---|---|
| Dell | F2 | F12 |
| HP | F10 | Esc |
| Lenovo | F1, F2 | Fn+F2 |
| ASUS | Delete, F2 | Esc |
