Both methods let you prepare Windows 10 installation media that works on any compatible PC. Here’s what you need to create your own bootable Windows 10 installer drive and how to do it.

What You’ll Need to Create a Bootable Windows 10 USB?
To create a Windows 10 bootable USB, you’ll need a USB drive (at least 8GB) and the Media Creation Tool from Microsoft. The tool downloads the necessary Windows 10 files and creates the bootable USB drive. In addition Internet connection is required to download the latest Windows 10 files from the Microsoft server.
- A USB Flash Drive: At least 8 GB of storage. (Be aware that all data on this drive will be erased during the process, so back up any important files before starting.)
- A Working PC: To download the tool and create the installation media.
- Stable Internet Connection: For downloading Windows 10 ISO or using the Media Creation Tool.
- Windows 10 Product Key (Optional): If you’re doing a clean install, you may need it for activation.
Create a Windows 10 Bootable USB Using Media Creation Tool
Microsoft has an official Media Creation Tool that you can use to download the Windows 10 system image (also referred to as ISO) and create your bootable USB drive.
Go to the official Windows 10 Download page here. Look for the section titled “Create Windows 10 installation media.” Click on the link to download the Media Creation Tool.

- Once the download is complete, locate the file and double-click it to run the tool.
- If a User Account Control prompt appears asking for permission, click Yes to allow the program to make changes to your device.
- Wait while the tool prepares, then click Accept on the license agreement screen.

- Next, you will be asked what you want to do. Select “Create installation media (USB flash drive, DVD, or ISO file) for another PC”, then click Next.
- This ensures the tool prepares the files needed for a clean installation on a different computer.

- The next screen allows you to customize the language, edition, and architecture (32-bit or 64-bit) of Windows 10. By default, the tool selects the same settings as your current PC.
If you want to change any of these—for example, to create a 64-bit version for a newer PC or to include both 32-bit and 64-bit versions—uncheck the box labeled “Use the recommended options for this PC.” Then, from the drop-down menus, choose the appropriate language, edition (such as Windows 10 Home or Pro), and architecture. Click Next when done.

Now, choose the type of media you want to create. Select the option “USB flash drive” and click Next. Make sure your USB drive is inserted into a USB port on your computer.

The tool will detect connected USB drives. From the list, select the correct USB drive by checking its name and size. Be very careful to select the right drive, as all data on it will be erased. After selecting the drive, click Next.

It will start downloading the Windows 10 installation files from Microsoft’s servers. Once the download is complete, the tool will automatically start writing the files to the USB drive and configure it to be bootable.

- This process can take anywhere from 10 to 30 minutes or more, depending on your internet speed.
- When the process finishes, a message will appear saying “Your USB flash drive is ready.” Click the Finish button.

Before removing the USB drive, right-click on it in File Explorer and choose “Eject,” or use the Safely Remove Hardware option in the system tray to avoid data corruption.
Create a Bootable Windows 10 USB with Rufus
Also, you can create Windows 10 bootable USB using the third-party application Rufus. It’s a free and open-source portable application for Microsoft Windows that helps format and create bootable USB flash drives or Live USBs.
- Download Rufus from the official website at rufus.ie (Make sure to use the correct site to avoid fake or malicious versions.).
- The tool is portable, so no installation is needed. Once downloaded, connect a USB flash drive with at least 8 GB of storage to your computer.
- Launch Rufus by double-clicking the executable file, and if prompted by User Account Control, click “Yes” to allow it to run.
- In the Rufus interface, ensure your USB drive is selected in the “Device” dropdown. Then, under “Boot selection”, choose “Disk or ISO image”, and click the “SELECT” button.

- If you already have a Windows 10 ISO file, browse and choose it. If not, click the download icon (a small cloud with a downward arrow) next to the “SELECT” button.
- Rufus will let you choose the Windows 10 edition, language, and architecture (32-bit or 64-bit), then automatically download the ISO from Microsoft’s servers.

Next, configure the partition scheme based on the target PC. For modern systems with UEFI firmware, set the partition scheme to GPT and the target system to UEFI (non CSM).
For older computers with legacy BIOS, choose MBR and BIOS or UEFI-CSM. Rufus usually sets the correct file system automatically—FAT32 for UEFI and NTFS for BIOS (especially if the ISO is over 4 GB).
Once everything is set, click “START”. A warning will appear stating that all data on the USB drive will be erased. Confirm by clicking “OK”.
Rufus will format the drive, write the Windows 10 installation files, and make it bootable. This process typically takes 10 to 20 minutes, depending on your USB speed and system performance.
When Rufus shows a “READY” status, the bootable USB is complete. Close the program and safely eject the USB drive.
