How to Install Windows 11 on DELL Latitude 5420 from USB

Preparing the Bootable USB Drive

• 💡 Download the Windows 11 ISO directly from the official Microsoft website to ensure authenticity.
• 🛠️ Use Rufus (rufus.ie) to create a bootable USB drive from the downloaded ISO file.
• ⚠️ Ensure you select the correct USB drive in Rufus, as all existing data on it will be erased.
• 💻 The Rufus tool should be run on a working Windows device; the architecture (x64 or x86) should match the device you are using to create the USB, not necessarily the Dell Latitude 5420.

BIOS and Boot Menu Configuration

• 🔌 Shut down your DELL Latitude 5420 completely, then plug in the prepared bootable USB drive.
• 🚀 Immediately after powering on, repeatedly press F12 to access the one-time boot menu.
• 🎯 Select your USB drive from the UEFI boot devices list to initiate the Windows installation.

Windows Installation Process

• 🗑️ During setup, navigate to the disk selection screen and delete all existing partitions on the target drive (likely Disk 0) to ensure a clean installation.
• ✅ Select the resulting unallocated space on the correct disk and proceed with the installation.
• ⏳ The installation process will involve several restarts; do not interrupt these cycles.

Initial Setup and Updates

• 🌐 Connect to a Wi-Fi network during the initial setup for crucial driver and Windows updates.
• ⚙️ Configure your region, keyboard layout, and accept license terms.
• 💻 Choose to set up for personal use unless you are logging in with a specific organization's account.
• 🔄 The system will check for and install updates, which may take a significant amount of time. Ensure the laptop remains plugged into power throughout this process.

Account and Finalization

• 🔑 Sign in with your Microsoft account or follow alternative guides to set up a local account.
• 🔒 Create a PIN for easier login and configure privacy settings according to your preferences.
• 💾 Choose whether to restore data from a previous backup or set up the PC as new.
• ✨ After the initial setup, navigate to Settings > Windows Update to check for and install any remaining updates for optimal performance.
