Troubleshooting UEFITool's Grayed Out Image Modification Options in A67

====================================================================================

UEFITool is an essential tool for developers working with Unified Extensible Firmware Interface (UEFI) firmware images. However, some users have encountered issues when attempting to modify these images using the latest versions of UEFITool, particularly on systems based on Intel's Z68 and H77 chipset families codenamed 'C65' or 'A67'.

One such problem is encountering grayed out options for modifying a UEFI image within UEFITool. This article aims to provide guidance on resolving this issue.

UEFITool Prerequisites

------------------

Before diving into the solution, ensure that you have satisfied all of the necessary prerequisites:

1. You are running an x86_64 architecture operating system (Windows 10 or later recommended).

2. UEFITTool version A67 is installed from a trusted source.

3. Your UEFI firmware supports Secure Boot.

Troubleshooting Steps

-------------------

### Step 1: Inspect Image Compatibility

First, verify that the image you are attempting to modify with UEFITool is compatible with your system architecture (32-bit or 64-bit). In some cases, mismatched architectures can lead to grayed out options.

### Step 2: Check for Corrupted Firmware

Corruption within the firmware itself could be responsible for this behavior. Try reflashing a fresh copy of your UEFI image using either an external flash programmer or Intel's Flash Programming Tool (FPT.EXE). If you are still experiencing issues after re-flashing, proceed to step 3.

### Step Secure Boot and Legacy BIOS Settings

Ensure that both the motherboard's firmware settings and the operating system boot configuration have been configured correctly.

1. Enter UEFI Setup by pressing the correct key during system POST (usually F2 or Del).

2. Navigate to 'Advanced' or 'Security'.

3. Set 'Secure Boot' to Disabled.

4. Save changes and exit UEFITool.

### Step 5: Disable Secure Flash Write Protection

Some systems may have secure flash write protection enabled in the firmware settings, which can prevent modifications even when Secure Boot is disabled. Check your motherboard's manual or manufacturer support resources for instructions on how to disable this feature if necessary.

-------

After following these steps and ensuring that all prerequisites are met, you should now be able to successfully modify UEFI images within UEFITool A67 without encountering grayed out options. If the issue persists despite attempting each of these troubleshooting measures, consider seeking further assistance from either Intel's forums or contacting your motherboard manufacturer for additional support.
