How to Create a Windows 10 Boot USB Drive

What you need before you start

A Windows 10 boot USB is a portable drive that starts your computer and lets you install Windows 10, repair an existing installation, or recover your system. To create one, you need three things: a USB drive with at least 8 GB of storage space, a computer that already has Windows 10 or Windows 11 installed, and the Windows 10 Media Creation Tool — a free program from Microsoft.

The USB drive will be erased during this process, so move any files you want to keep to another location first. The computer you use to create the boot drive does not have to be the one you plan to install Windows 10 on — you just need one that works right now.

Plug the USB drive into the computer you are using to create the boot drive. Windows will recognize it as a removable storage device. You do not need to format it yourself; the Media Creation Tool will handle that.

Key Takeaways

Download the Windows 10 Media Creation Tool directly from Microsoft's website, not from a third-party site.
The tool will erase your USB drive, so back up any files on it before you start.
The entire process takes 15 to 30 minutes depending on your internet speed and USB drive speed.
Once the boot drive is ready, you can use it on any computer by plugging it in and restarting.

Download the Media Creation Tool from Microsoft

Go to microsoft.com/software-download/windows10 in your web browser. This is Microsoft's official download page for Windows 10. You will see a button labeled "Download tool now" — click it to save the Media Creation Tool to your computer.

The file will be named MediaCreationTool.exe. Once it finishes downloading, open your Downloads folder and double-click the file to run it. Windows may ask if you want to allow this program to make changes to your device — click "Yes" to proceed.

The tool will open and ask you to accept the Microsoft Software License Terms. Read through it if you want, then click "Accept" at the bottom to continue.

Select "Create installation media for another PC"

The Media Creation Tool gives you two options: upgrade this PC or create installation media. You want the second option. Click the radio button next to "Create installation media (USB flash drive, DVD, or ISO file) for another PC" and then click "Next".

The tool will then ask you to choose the language, edition, and architecture for Windows 10. The default settings usually match what you need — English, Windows 10, and 64-bit. If your computer uses 32-bit Windows or you need a different language, change it here. Most modern computers use 64-bit, so leave it as is unless you have a specific reason to change it.

Click "Next" after you have set the language and edition.

Choose USB flash drive as your media type

The tool will ask what media you want to use. You have three options: USB flash drive, DVD, or ISO file. Select "USB flash drive" and click "Next".

The tool will then show you a list of removable drives connected to your computer. Find your USB drive in the list — it will show the drive letter (like D: or E:) and the storage capacity. Click on it to select it, then click "Next".

The tool will warn you that everything on the selected drive will be deleted. This is normal. Click "Next" to confirm and begin the process.

Wait for the tool to finish writing to the USB drive

The Media Creation Tool will now download Windows 10 files and write them to your USB drive. This step takes the longest — usually 15 to 30 minutes depending on your internet speed and how fast your USB drive is. Do not unplug the drive or close the tool during this time.

You will see a progress bar showing the download and writing process. The tool will first download the Windows 10 files, then format your USB drive, then copy the files to it. Let it run until you see a message saying the media creation is complete.

Once the tool finishes, it will show a screen saying "Your USB flash drive is ready". Click "Finish" to close the tool and eject the USB drive.

Eject the USB drive safely

Before you unplug the USB drive, eject it properly through Windows. Right-click on the USB drive in File Explorer and select "Eject". Wait for Windows to confirm the drive is safe to remove, then unplug it from the computer.

Your Windows 10 boot USB is now ready to use. You can plug it into any computer, restart that computer, and boot from the USB drive to install Windows 10 or access repair and recovery tools. The drive will work on both Windows and Mac computers.

What to do if the tool gets stuck or fails

If the Media Creation Tool stops responding or shows an error message, close it and try again. Make sure your USB drive is plugged directly into a USB port on the computer — not into a USB hub, which can cause connection problems. Also check that the USB drive has at least 8 GB of free space.

If the download fails partway through, the tool will usually resume from where it stopped when you run it again. If it keeps failing, your internet connection may be unstable — try again later or use a different network if possible.

If you see an error about the drive being write-protected, the USB drive itself may have a physical lock switch on the side. Check for a small switch and flip it to the unlocked position, then try again.

Frequently Asked Questions

Can I use this boot drive on multiple computers?

Yes. Once you create the boot USB, you can plug it into any computer and use it to install Windows 10 or access recovery tools. The drive itself is not tied to any specific computer.

Will creating a boot drive delete files on my computer?

No. The Media Creation Tool only erases the USB drive itself, not your computer's hard drive. Your computer files are safe. However, if you later use this boot drive to install Windows 10 on a computer, that installation process will erase the target computer's drive.

Do I need an internet connection to use the boot drive after it is created?

You need internet during the creation process to download Windows 10 files. Once the boot drive is ready, you can use it on any computer without internet. However, you will need internet after Windows 10 installs to download drivers and updates.

What if my computer will not boot from the USB drive?

Your computer's BIOS or UEFI settings control which devices it boots from. Restart the computer and watch for a message saying "Press F2", "Press Del", or "Press F12" to enter setup — the key varies by manufacturer. Enter setup and look for a boot order or boot device menu, then move the USB drive to the top of the list.

Can I use a USB 2.0 drive instead of USB 3.0?

Yes, but it will be slower. USB 2.0 drives work fine for creating and using a Windows 10 boot drive — they just take longer to write the files and longer to install Windows. USB 3.0 is faster but not required.
