How to Check if PC Is Uefi

Are you wondering whether your PC is running on UEFI or the traditional BIOS? It's simpler to check than you might think. You can quickly peek into your system's firmware through a few straightforward steps. For instance, during the boot process, entering the BIOS setup can give you immediate clues—just keep an eye out for terms like "UEFI" in the boot options. Alternatively, Windows offers tools like the System Information where a quick look under 'System Summary' can reveal the BIOS Mode. Curious about what this means for your system's performance or future upgrades? Let's explore how these settings impact your PC's capabilities.

Accessing BIOS Settings

To access your PC's BIOS settings, restart it and press the designated key, such as F2, Del, or Esc, as soon as the startup screen appears. This initial phase is important; timing is key as the window to enter BIOS setup is typically short.

Once inside the BIOS menu, navigate to the boot or firmware settings. Here, you'll find whether your system operates in UEFI mode or Legacy BIOS. UEFI generally provides more advanced features like secure boot and faster boot times, essential for newer Windows operating systems.

Identifying whether your PC utilizes UEFI or Legacy BIOS helps ensure compatibility and peak performance with the operating system you choose to deploy.

Using Windows System Information

Launch the Windows VM and type 'msinfo32' in the Taskbar search to open System Information. This tool is essential for verifying your PC's firmware mode, especially if you're evaluating Windows 11 compatibility or optimizing boot times.

Here's what you need to check:

  1. BIOS Mode: Under the 'System Summary', find the 'BIOS Mode' entry. This will indicate whether your system is using Legacy or UEFI firmware.
  2. UEFI Benefits: If it shows UEFI, your system supports larger drives and faster boot processes, essential for modern computing needs.
  3. Secure Boot: Look for the 'Secure Boot State'. It should be enabled for UEFI systems, a requirement for the full security benefits of Windows 11.

Checking Disk Partitions

If you're investigating whether your PC uses UEFI or Legacy BIOS, checking the disk partition style is an essential step. Open the Disk Management tool by pressing Windows key + X and selecting 'Disk Management.' Here, you'll see your disk listed. Right-click on the disk and choose 'Properties,' then navigate to the 'Volumes' tab.

Look for the 'Partition style' entry. If it reads 'GUID Partition Table (GPT),' your system likely uses UEFI. Conversely, if it shows 'Master Boot Record (MBR),' you're probably dealing with a Legacy BIOS setup. Additionally, check for an 'EFI System Partition' which confirms UEFI, while a 'System Reserved Partition' often indicates Legacy BIOS. This distinction in the partition table format is critical for understanding your BIOS firmware type.

Examining Setupact.log File

After checking the disk partition style, you can further verify your PC's firmware type by examining the setupact.log file in the C:\Windows\Panther folder. Here's how to do this:

  1. Open File Explorer: Navigate to the `C:\Windows\Panther` directory.
  2. Access the setupact.log: Open this text file using Notepad to view the details.
  3. Search for Keywords: Look for the phrase 'Detected boot environment'. This section will indicate whether the system uses UEFI or Legacy BIOS. Key details are found under the 'Windows Boot Loader' section if it's UEFI, or 'BIOS Boot' if Legacy.

This method is precise and will confirm the type of firmware your system was installed with.

Using Command Prompt

To determine if your PC utilizes UEFI or Legacy BIOS, follow these steps:

  1. Open Command Prompt.
  2. Execute the command `bcdedit | find 'path'`.

This command inspects the configuration data of the Windows Boot Loader, specifically searching for the file path. Look for the file `\Windows\system32\winload.exe` in the output. The presence of this file indicates that your PC is operating under UEFI mode; its absence suggests Legacy BIOS mode.

This method provides a straightforward approach to verify your PC's firmware interface type, essential for compatibility with modern operating systems like Windows 11, which require UEFI support. Using Command Prompt for this check is efficient, bypassing the need for BIOS menu navigation.
