. In this instance, I want to install a fresh copy of Windows 10 onto my Surface, so lets get started.. First of all, you will want to ensure that your USB device that you will be booting from is formatted as FAT32. The first time around I had my USB drive formatted as NTFS, and it was completely ignored by the Surface. If your Surface is not already off shut it down. Now. Plug your bootable USB media that you have created into the USB port. On the right hand, side of the Surface., While the Surface is off, hold down the Volume Up button. That is the button with the icon on the top., While still holding the volume up button press the power button once and let go of the power button. But do not let go of the volume up button just yet. The screen should show the Surface text keep holding the volume up button. Until you see the Surface UEFI screen as shown. From the menu on the left, select Boot Configuration. To change the order, simply select USB Storage and drag it to the top so that it has the highest priority. Once complete, select Exit from the left.. The Surface will note that all changes have been saved, so click the Restart Now button.. The Surface should now boot from the attached USB device. In my case, it has successfully started up the Windows 10 installation process as expected. Thats. All there is to it.

You should now be able to boot from USB media with your Surface Pro 4..
