Troubleshooting UEFI Access Issues on HP EliteDesk 800 G5 SFF

Introduction

Accessing the Unified Extensible Firmware Interface (UEFI) is a crucial step when configuring BIOS settings, installing new operating systems, or performing hardware diagnostics. However, some users encounter difficulties entering the UEFI interface on their PCs. This article addresses common challenges faced with the HP EliteDesk 800 G5 Small Form Factor (SFF) and provides guidance on troubleshooting and resolving UEFI access issues.

Scenario Overview

A user with an HP EliteDesk SFF 800 G5, running Windows 11, reported an inability to access UEFI during startup. Traditional methods—such as pressing function keys (F2, F10, F12), the Escape key, or attempting to trigger Advanced Startup options—proved ineffective. Restarting the system via Windows’ advanced options resulted in a blank or unresponsive screen. The user expressed uncertainty about alternative methods to access UEFI or resolve this issue.

Potential Causes

Several factors can contribute to this problem:

1. Fast Boot or Secure Boot Settings: These features can delay or bypass the UEFI menu.
2. Incorrect or Faulty Key Sequences: Different manufacturers assign various keys to access BIOS/UEFI.
3. Windows Fast Startup: May interfere with early hardware initialization.
4. Firmware or BIOS glitches: Outdated firmware can hinder standard procedures.
5. Hardware anomalies or hardware changes: Recent hardware modifications might affect boot sequences.

Recommended Solutions

1. Disable Fast Boot and Secure Boot

2. Boot into Windows.

3. Navigate to Settings > Update & Security > Recovery.
4. Under Advanced Startup, click “Restart Now.”
5. Upon restart, select Troubleshoot > Advanced options > UEFI Firmware Settings.
6. Click “Restart,” which should take you directly into the UEFI settings.

Note: If this pathway is inaccessible, proceed to other methods.

1. Use the Platform Firmware Update (PFU) Utility

2. Visit the HP Support website.

3. Download and install the latest BIOS update for your HP EliteDesk 800 G5.

4. Follow the update instructions carefully. Sometimes, updating BIOS can resolve hardware communication issues preventing UEFI access.

5. Initiate UEFI Access During Boot

6. Power off the system completely.

7. Turn it on and immediately press the BIOS access key repeatedly—commonly F10 or Esc for
