Troubleshooting Windows 11 Upgrade Challenges on Dell XPS 15 7590: Overcoming Installation Failures During the SAFE_OS Phase

Upgrading to Windows 11 can be a straightforward process for many users, but some encounter persistent issues that hinder a smooth transition. One common problem reported by Dell XPS 15 7590 owners involves the upgrade failing during the installation phase, specifically citing the error message: “The installation failed in the SAFE_OS phase with an error during INSTALL_DRIVERS operation.”

In this article, we explore this particular problem, discuss common causes, and outline potential solutions to help you upgrade to Windows 11 without resorting to a complete clean installation.

Understanding the ERROR: SAFE_OS PHASE and INSTALL_DRIVERS

The Windows upgrade process is complex, involving multiple phases. The SAFE_OS (Safe Operating System) phase is critical, involving system preparations and driver installations. When an error occurs during INSTALL_DRIVERS, it typically indicates issues with device drivers, incompatible hardware, or outdated components that prevent the upgrade from completing successfully.

Common Causes of the Error

• BIOS firmware that needs updating
• Peripheral devices connected during upgrade
• Corrupted Windows or System Files

Preliminary Troubleshooting Steps

1. Disconnect External Devices

Ensure all peripherals—USB drives, printers, external monitors, or other connected devices—are unplugged during the upgrade process. Even seemingly benign devices can interfere with driver installation.

1. Update Windows and Drivers

2. Run Windows Update to ensure your current system is fully updated.

3. Visit Dell’s official support website for the XPS 15 7590 to download the latest drivers and BIOS firmware.

4. Update device BIOS and firmware before attempting the upgrade again.

5. Disable Unnecessary Startup Applications
