✅ Enterprise‑ready architecture – Close to real production deployments

Whether you are building a personal homelab, preparing for a system administrator role, or validating new Windows Server features, this setup gives you full control and long‑term scalability.

⚙️ What You’ll Learn in This Demo

This guide focuses on practical configuration instead of theory. By the end of this tutorial, you will be able to reproduce the setup in your own environment.

📌 Create a new virtual machine on Proxmox VE
📌 Configure CPU, RAM, storage, and network interfaces
📌 Attach the Windows Server 2025 ISO file
📌 Install Windows Server 2025 step by step
📌 Complete the first successful boot and initial setup

Each step reflects a real‑world lab configuration that can later be extended for advanced services.

🧩 Lab Overview

In this demo, Windows Server 2025 is deployed as a KVM virtual machine on Proxmox VE. The configuration is optimized for stability and future expansion, allowing you to reuse the same VM for upcoming labs such as:

• Active Directory Domain Services

• DNS and DHCP

• Group Policy Management

• File Server and Storage Services

• Backup and recovery testing

This approach ensures that the environment you build today remains useful throughout the entire WinServer2025 learning series.

🛠️ Step‑by‑Step Installation Flow

The technical steps and commands remain exactly the same as demonstrated in the video. This article reorganizes the structure for clarity while preserving the original technical flow.

Step 1: Prepare Proxmox VE Environment

Ensure that Proxmox VE is installed, accessible via the web interface, and has sufficient resources available for a Windows Server virtual machine.

Step 2: Upload Windows Server 2025 ISO

Upload the official Windows Server 2025 ISO to the Proxmox ISO storage so it can be attached to the virtual machine during installation.

Step 3: Create a New Virtual Machine

Define the virtual machine parameters, including:

• VM name and ID

• System type and BIOS settings

• CPU cores and memory allocation

• Disk type and storage location

• Network bridge configuration

These settings are chosen to balance performance and compatibility.

Step 4: Attach Installation Media

Mount the Windows Server 2025 ISO to the virtual CD/DVD drive of the VM and verify that the boot order is correctly configured.

Step 5: Install Windows Server 2025

Follow the Windows Server installation wizard step by step, selecting the appropriate edition and disk configuration until the setup completes successfully.

Step 6: First Boot Verification

After installation, confirm that Windows Server 2025 boots correctly, detects hardware properly, and is ready for post‑installation configuration.
