Resolution

To determine whether your PC is using Legacy BIOS or EFI/UEFI please follow the steps below:

 

1. Start your PC

2. Go to Start  ► Computer

3. Navigate to C:\Windows\Panther\setupact.log

4. Open setupact.log

5. Search for this string:

 

Callback_BootEnvironmentDetect: Detected boot environment:

 

The entry found in the Setupact.log should show the boot environment: BIOS or UEFI:

 

Examples

 

Code:Callback_BootEnvironmentDetect: Detected boot environment: BIOS

Code:Callback_BootEnvironmentDetect: Detected boot environment: UEFI

 

Another method to determine if the machine is using BIOS or UEFI that will work on Windows operating systems is to use the MSINFO32.exe utility which is built in.

 

1.  Navigate to Start and either use the RUN line or open a Command Prompt.

2.  Type in MSINFO32.exe and click Enter.

3.  The System Information Report will open on the screen.

4.  In 'System Summary' find the line with 'BIOS Mode' and it should show either UEFI or Legacy.
