How to Install Windows on a DELL Precision 5520: Step-by-Step Guide

Preparing for Windows Installation

• 💡 Before starting, ensure you have a USB drive (at least 8GB) and another Windows device if your Dell Precision 5520 is not accessible.
• ⚠️ Reasons for installation include forgotten passwords, corrupted systems, or simply desiring a fresh Windows installation.

Downloading Necessary Files

• 🚀 Download the Windows 11 ISO file by searching for "Windows 11 ISO" and selecting the multi-edition ISO, choosing your preferred language and 64-bit version.
• 🛠️ Download Rufus from rufus.ie to create a bootable USB drive.
• 💻 Obtain the specific Wi-Fi driver for your DELL Precision 5520 by entering its service tag on the Dell support website, as this driver is crucial for internet connectivity post-installation.

Creating a Bootable USB Drive

• 🔌 Plug in your USB drive and open Rufus. Select the USB device and the downloaded Windows 11 ISO image.
• ✅ Click "Start" in Rufus, confirm any prompts (unselecting optional offers if desired), and allow Rufus to create the bootable USB drive.
• 📂 After Rufus completes, copy the downloaded Wi-Fi driver file directly onto the bootable USB drive.

Installing Windows on DELL Precision 5520

• ⚡ Shut down your Dell Precision 5520, plug in the bootable USB drive, and power it on.
• ⌨️ Immediately press F12 repeatedly to access the boot menu and select the USB drive (often labeled UFI generic or similar).
• 🗑️ During the Windows setup, navigate to the disk management section. Select your internal drive (Disk 0) and delete all existing partitions until it shows as unallocated space.
• 🖱️ Select the unallocated space on Disk 0 and proceed with the Windows installation.

Installing Wi-Fi Driver and Finishing Setup

• ⚠️ If the touchpad doesn't work, use the keyboard for navigation. Select your language and keyboard layout.
• 🆘 If the Wi-Fi driver isn't automatically installed, press Shift + F10 to open the command prompt.
• 💻 Navigate to your USB drive (e.g., D:), type "intel" and press Tab to auto-complete the driver name, then press Enter to install the driver.
• 🌐 Once the Wi-Fi driver is installed, you should see Wi-Fi options. Connect to your network, and Windows will continue with updates and final setup.
