To access and install Windows 11 Pro from a USB flash drive, first create proper Windows 11 installation media, then boot from it.

  1. Create a Windows 11 USB installation drive
    1. On a working Windows PC, go to the Windows 11 software download page: Download Windows 11.
    2. Under Create Windows 11 Installation Media, select Download Now to get MediaCreationTool.exe.
    3. Run MediaCreationTool.exe and accept the license terms.
    4. Follow the wizard to:
      • Select language and edition (choose Windows 11; Pro will be selectable during install if the device/license supports it).
      • Choose USB flash drive as the media type.
      • Select the USB drive (must be at least 8 GB; any existing data on it will be erased).
    5. Let the tool finish creating the bootable USB.
  2. Boot the PC from the USB drive
    1. Shut down the PC where Windows 11 Pro will be installed.
    2. Insert the Windows 11 USB installation drive.
    3. Turn on the device and immediately open the boot menu (usually a function key like F1–F12 or DEL, depending on the manufacturer).
    4. In the boot menu, select the USB drive as the boot device.
  3. Install Windows 11 Pro from the USB
    1. When the Windows 11 Setup screen appears, choose language, time, and keyboard layout.
    2. Select Install now.
    3. When prompted for edition, choose Windows 11 Pro (if available for the license/key being used).
    4. For a clean install, choose Custom: Install Windows only (advanced) and select the target drive/partition.
    5. Follow the remaining on-screen instructions until setup completes.

If the USB is “not accessible” (for example, not booting or not recognized), typical causes are:

  • The USB was not created with the official media creation tool.
  • The PC is not set to boot from USB (boot menu or BIOS/UEFI boot order not configured).
  • The USB drive is faulty or too small.

Using the official Windows 11 installation media method ensures the USB is correctly prepared and bootable.

Hi,

To better understand the issue and guide you to the right solution, could you please clarify the following:

Did you purchase a Windows 11 Pro license, or did you purchase a USB flash drive that was supposed to contain the Windows 11 Pro installation files?

What exactly happens when you try to access the USB flash drive?

Are you receiving any error messages? If so, please share the exact error message.

Are you trying to install Windows 11 Pro on a new computer, or are you trying to upgrade an existing Windows installation?

Hello

The AI answer does give the general instruction.

Since you mentioned specifically "Pro", if the computer has OEM license onboard for Home edition, the above instruction will install Home automatically.

Let me know if this could be the case why you specifically asked for Pro install, if so, I am happy to provide further modified instruction.

To install Windows 11 Pro using a USB flash drive, follow these steps.

  1. On a working Windows PC, go to the Windows 11 software download page: https://www.microsoft.com/software-download/windows11.
  2. Under Create Windows 11 Installation Media, select Download Now and run the media creation tool.
  3. Accept the license agreement and select Next.
  4. Follow the instructions in the tool to create a bootable USB drive with the Windows 11 installation files (ensure the USB drive has at least 8 GB and no important data, because it will be formatted).
  5. When the tool finishes, safely remove the USB drive.

On the PC where Windows 11 Pro will be installed:

  1. Insert the bootable USB drive.
  2. Power on the device and immediately press the key that opens the boot menu (commonly a function key such as F1–F12 or DEL; check the device documentation if needed).
  3. From the boot menu, select the USB drive so the PC boots from it.
  4. When the Windows 11 setup UI appears, choose language, time, and keyboard settings, then select Install now.
  5. When prompted for edition, select Windows 11 Pro (if multiple editions are available).
  6. Follow the on‑screen instructions to either:
    • Upgrade an existing Windows installation, or
    • Perform a clean install by deleting existing partitions and installing Windows 11 Pro on the unallocated space.
  7. Complete the setup steps (region, account, etc.) after installation finishes.

If using a Surface Hub 3, the same USB method applies, but the boot sequence is specific:

  1. After creating the bootable USB as above, insert it into Surface Hub 3.
  2. Press and hold Volume down, then press Power. Keep both pressed until the Windows logo appears.
  3. Release Power but keep holding Volume down until the Install UI begins.
  4. Follow the on‑screen instructions and select Windows 11 Pro when prompted.

Hello,

This issue is not related to Windows for Business or Windows 365 Enterprise. It is specifically about obtaining the official installation media for Windows 11 Pro.

To perform a clean install, you need to download the Windows 11 Media Creation Tool directly from Microsoft. The tool allows you to create bootable USB or ISO media that can be used to install Windows 11 Pro. The download is available on Microsoft’s official site under the “Download Windows 11” section. Once you run the tool, you can select “Create installation media (USB flash drive, DVD, or ISO file) for another PC.” During installation, the edition will be determined by the product key you enter. If you provide a Windows 11 Pro key, the setup will install Pro rather than Home.

Here is the official Microsoft download page: microsoft.com/en-us/software-download/windows11

Make sure you have a valid Windows 11 Pro license key ready, as the Media Creation Tool itself does not provide a key—it only prepares the installation media. If your device already has a digital entitlement for Pro, the installer will automatically recognize it during setup.

I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!

Domic Vo.
