How to Mount EFI in Windows 11
The EFI (Extensible Firmware Interface) system is a standard interface between a computer’s firmware and its operating system. It is used to boot the operating system and manage hardware devices. In Windows 11, the EFI system is located on a partition called the EFI System Partition (ESP). This partition is typically hidden by default, but you can mount it to view its contents.
There are a few reasons why you might want to mount the EFI system partition. For example, you may need to access the EFI Boot Manager to change the boot order of your system. Or, you may need to troubleshoot a problem with your computer’s firmware.
In this article, I will show you how to mount the EFI system partition in Windows 11. I will also provide a brief overview of the EFI system and its role in the boot process.
What is the EFI System Partition?
The EFI System Partition (ESP) is a small partition (typically 100 MB) that is created when you install Windows 11. The ESP contains the EFI firmware, which is responsible for booting the operating system. It also contains the boot loader, which is a small program that loads the operating system into memory.
The ESP is typically hidden by default, but you can mount it to view its contents. To do this, you can use the Disk Management tool or the Command Prompt.
How to Mount the EFI System Partition
There are two ways to mount the EFI System Partition in Windows 11:
- Using the Disk Management tool:
1. Open the Disk Management tool by pressing Windows+X and selecting Disk Management.
2. Right-click the EFI System Partition and select Mount.
3. In the Mounted Location box, type a drive letter for the EFI System Partition.
4. Click OK.
- Using the Command Prompt:
1. Open the Command Prompt by pressing Windows+R and typing cmd.
2. Type the following command:
mountvol X: /s
where X is the drive letter you want to use for the EFI System Partition.
What is the EFI Boot Manager?
The EFI Boot Manager is a small program that is stored on the EFI System Partition. The EFI Boot Manager is responsible for loading the operating system into memory.
When you start your computer, the EFI Boot Manager is the first program that is executed. The EFI Boot Manager scans the EFI System Partition for bootable operating systems. When it finds a bootable operating system, it loads the operating system into memory.
How to Access the EFI Boot Manager
To access the EFI Boot Manager, you can use the following steps:
1. Restart your computer.
2. Press the F2 key or the Delete key repeatedly during the boot process.
3. The EFI Boot Manager will be displayed.
4. Use the arrow keys to select the operating system you want to boot.
5. Press Enter to boot the operating system.

On Windows 11, the EFI System Partition, as on Linux distros, contains the boot manager files. On a Linux distro, the partition is mounted on the /boot/efi folder, so accessing its contents is as easy and simple as typing cd /boot/efi or ls /boot/efi. On Windows 11, however, the EFI System Partition is not even assigned a drive letter, so its contents are off limits.
In this tutorial, you learn learn how to assign a drive letter to the EFI System Partition on Windows 11, so that you can then access its contents from the PowerShell or command prompt terminal.
step 1: Assign a drive letter to the EFI System Partition
You’ll be completing this step from a PowerShell terminal. To launch the terminal application, type in terminal in the search field of the Windows 11 taskbar. Right-click on it and select Run as administrator. All the PowerShell commands you need to complete this step are red-arrowed in Figure 1. PowerShell has command completion, so you do not have to type in every letter of each command.
Get-Disk, the first command you’ll type, outputs all the drives available on the system. In my case, only a single drive was found – Number 0. Then type Get-Partition -DiskNumber 0 to output all the partitions configured on that drive. Studying the command’s output, you can tell that the EFI System Partition is PartitionNumber 1.
Now you can assign that partition a drive letter using the following command: Set-Partition -NewDriveLetter E. You can change the “E” to a drive letter that’s not already in use on your system.
Figure 1: PowerShell commands to use when trying to assign a drive letter to the EFI System Partition on Windows 11.
Now that the EFI System Partition has a drive letter, you’ll see how easy it is to access its contents in the next step.
step 2: Access the EFI System Partition using PowerShell
With a drive letter assigned to it, its now easy and simple to access the EFI System Partition from within a PowerShell terminal launched as administrator. You can type ls E: or first cd E: and then an ls command to access and view the contents of the EFI System Partition. Critical boot files are in the EFI folder , so you can view the contents of that folder using the ls EFI command. If you study the output of that command in Figure 2, you can tell that I’m dual-booting Windows 11 and a Linux distro. That distro, by the way, is Linux Mint 22, with the distro installed on an external drive.
Figure 2: Accessing the EFI System Partition on Windows 11 from PowerShell.
In the next step, you’ll learn how to access the the same EFI System Partition using the traditional Windows command prompt.
step 3: Access the EFI System Partition using command prompt
While PowerShell presents a more user-friendly interface for working in the Windows 11 terminal application, you can still perform the same tasks in the traditional Windows command prompt. If you have the terminal application still open as administrator, you can open the command prompt in a shell by pressing the Ctrl-Shift-2 key combination or by clicking on the chevron (the downward-pointing arrow) and selecting Command Prompt.
Otherwise, type in terminal in the search field of the Windows 11 taskbar. Right-click on it and select Run as administrator. Then open the command prompt using the above key combination or clicking on the chevron and selecting the appropriate option.
The commands to type in order to access the EFI System Partition are red-underlined in Figure 3.
Fig. 3: Commands used to access the EFI System Partition from the command prompt on Windows 11.
Can you access the EFI system partition from File Explorer?
After assigning a drive letter to the EFI System Partition, you should see it listed under This PC in the side panel of File Explorer.
Fig. 4: Windows 11 File Explorer showing an entry for the EFI System Partition in the side panel.
However, clicking on that entry will open the message window shown in Figure 5. What do you think will happen if you click the Continue button?
Fig. 5: File Explorer message after clicking on the EFI System Partition.
You’ll be denied permission to access the EFI System Partition from File Explorer.
Fig. 6: Permission denied message from File Explorer.
I’m guessing the reason it’s not possible to access the EFI System Partition from File Explorer is it was not launched as administrator. But this is not a big deal, since you can already access it using PowerShell or command prompt.
