Requirements Before You Begin
Before creating your bootable USB, make sure you have the following:
- A USB flash drive (at least 8GB, but 16GB or more is recommended).
- A working PC with internet access.
- Windows 11 ISO file or the Media Creation Tool from Microsoft.
- UEFI/BIOS compatibility on the target PC.
⚠️ Important: Creating a bootable USB will erase all data on the drive. Back up anything important first.
Method 1: Using Microsoft’s Media Creation Tool
This is the simplest and most reliable way to create a Windows 11 bootable USB.
Steps:
- Plug your USB drive into your PC.
- Go to Microsoft’s official website and download the Media Creation Tool.
- Run the tool and accept the license terms.
- Select Create installation media (USB flash drive, DVD, or ISO file) for another PC.
- Choose Language, Edition, and Architecture (64-bit) for Windows 11.
- Select USB flash drive as the media type.
- Pick your USB drive from the list and click Next.
- Wait while the tool downloads Windows 11 and creates the bootable USB.
When done, your USB will be ready to use as a Windows 11 installer.
Method 2: Using Rufus (Third-Party Tool)
If you prefer more control, Rufus is a popular tool for creating bootable drives.
Steps:
- Download Rufus from its official site.
- Insert your USB drive.
- Launch Rufus (no installation required).
- Under Device, select your USB drive.
- Click Select and choose the Windows 11 ISO file.
- For Partition scheme, choose GPT (for UEFI) or MBR (for Legacy BIOS).

- Click Start and wait for Rufus to create the bootable USB.
👉 Tip: Rufus also allows bypassing Windows 11’s TPM and Secure Boot requirements, which is useful for older PCs.
Method 3: Using Command Prompt (Manual Method)
For tech enthusiasts, you can manually create a bootable USB via Command Prompt.
Steps:
- Plug in your USB drive.
- Press Win + S, type
cmd, right-click, and run as Administrator. - Enter the following commands one by one:
diskpart list disk select disk X (replace X with your USB disk number) clean create partition primary select partition 1 active format fs=ntfs quick assign exit - Mount your Windows 11 ISO file.
- Copy all the contents of the ISO to your USB drive.
Congratulations—you’ve created a bootable USB manually!
Method 4: Using Windows USB/DVD Download Tool

Steps:
- Download and install the Windows USB/DVD Download Tool.
- Insert your USB drive.
- Open the tool and select your Windows 11 ISO file.

Once your USB is ready, you’ll need to boot from it to install Windows 11.

UEFI vs. Legacy BIOS: Which One Should You Choose?

- MBR (Master Boot Record) – Works with Legacy BIOS systems (older PCs).
👉 Most Windows 11 PCs use UEFI + GPT.
