Table of Contents

1. Platform requirements for Windows 11 Pro

Before you begin, make sure your PC is suitable. Windows 11 has more stringent requirements than previous Windows versions. Your platform must meet:

  • A 64-bit compatible processor (1 GHz or faster, 2+ cores)
  • Minimum 4 GB RAM (8 GB or more recommended).

  • UEFI firmware with Secure Boot
  • TPM 2.0 module (required for Windows 11)
  • DirectX 12 compatible graphics card
  • Screen of at least 9" and resolution 720p or higher

You can automatically check if your PC is suitable via Microsoft's genuine tool:


Download PC Health Check tool (MS)

2. Pre-installation preparation.

Create a full backup

A Windows installation can completely erase your disk, depending on your chosen method. So make a safe backup of:

  • Documents, photos, videos.
  • Browser favorites and passwords
  • Software Licences
  • Email details

Remove external peripherals

Leave only mouse, keyboard, monitor and network cable connected. Disconnect printers, extra hard drives and adapters to avoid installation problems.

Write down your Windows 11 Pro product key

Buy your Windows 11 Pro key from a trusted vendor and have your product key handy during installation.

3. Download Windows 11 Pro ISO

Always download through Microsoft to avoid errors and corrupt files. Never use torrent sites or unofficial downloads.

On this page, select "Download Windows 11 Disk Image (ISO File)" at the bottom . Then select:

  • Edition: Windows 11
  • Language (e.g., Dutch)
  • 64-bit download

4. Creating a bootable USB drive

To install correctly, you will need a USB flash drive of at least 8 GB. There are two safe methods:

  • Target → UEFI (non-CSM)

Click Start and wait for the USB flash drive to be fully prepared.
