A bootable Windows 10 USB contains Windows Setup files in a form the computer can start from. Creating one erases the USB drive, so copy anything important from it before you begin.
Create official Windows installation media
- Use a working Windows PC and an empty USB flash drive with sufficient capacity.
- Open Microsoft’s official Windows download resources rather than a third-party ISO or modified installer site.
- Run the supported media-creation process and choose the option to create installation media for another PC.
- Select the appropriate language, edition, and architecture when those choices are offered.
- Choose USB flash drive, select the correct removable drive, and let the tool finish writing the media.
- Safely eject the USB drive when creation is complete.
Booting from the USB is a separate step
To use the installer, connect it to the target PC and open that computer’s boot menu or UEFI interface using the manufacturer’s documented startup key. Selecting the USB can start Windows Setup.
Do not delete or format partitions during Setup unless you understand which disk and partition you are changing and have backed up required data.
Windows 10 lifecycle matters
Microsoft ended standard free Windows 10 support on October 14, 2025. A bootable Windows 10 USB can still be useful for an authorized legacy recovery or installation scenario, but for a PC that officially supports Windows 11, installing a supported Windows release is generally the better long-term choice.
