How to Install Windows 11 on DELL Latitude 3520 from USB: Step-by-Step Guide

Preparing for Windows Installation

• 💡 A USB flash drive with at least 8 GB of storage is required for the Windows 11 installation.
• 💻 You'll also need another PC to download the Windows 11 ISO and create a bootable USB drive.

BIOS Configuration for DELL Latitude 3520

• 🔑 Access the BIOS by pressing F2 repeatedly after powering on the laptop.
• ⚙️ Navigate to the storage section and ensure AHCI/NVMe is enabled. If RAID is checked or disabled, select the AHCI/NVMe option to ensure the system disk is visible during installation.
• 💾 Save changes in BIOS and turn off the laptop.

Creating a Bootable USB Drive with Rufus

• 🌐 Download the official Windows 11 ISO from the Microsoft website.
• 🛠️ Download the latest version of Rufus from rufus.ie.
• ⚠️ Insert your USB flash drive into the PC and open Rufus. Back up any existing data on the USB, as it will be formatted.
• 🖱️ Select your USB drive, then click 'Select' to choose the downloaded Windows 11 ISO image. Leave other settings as default and click 'Start'. Confirm the warning about data erasure.
• ✅ Wait for the process to complete, then safely eject the USB drive.

Booting from USB and Installing Windows

• 🔌 Insert the bootable USB into the DELL Latitude 3520 and power it on.
• 🚀 Press F12 repeatedly to access the one-time boot menu and select the UEFI generic USB30 option.
• ⏳ The Windows installation process will begin. Choose your language and keyboard layout, then accept the license agreement.

Disk Partition Management

• 💽 In the disk selection screen, you will see partitions. Delete the first four partitions if they exist to ensure a clean installation.
• 💾 You will be left with unallocated space. You can proceed by clicking 'Next' on the unallocated space to install Windows there.
• ➕ Alternatively, to create a separate partition for a second disk, click 'Create partition', input a desired size (e.g., 100-137 GB for the system disk), and click 'Apply'.
• ⏳ Click 'Install' and wait for Windows to be installed.

Post-Installation Setup

• ✅ Once the installation is complete, proceed through the initial Windows setup process.
• 🖱️ The touchpad should be functional, allowing you to complete the setup without needing to download separate drivers immediately.
