A: Most USB boot sticks are formatted as NTFS, which includes those created by the Microsoft Store Windows USB/DVD download tool. UEFI systems (such as Windows 8) can't boot from an NTFS device, only FAT32.

Therefore you need to create a bootable USB device that's formatted as FAT32 instead, then copy the contents of the Windows installation media to it. For example use the commands below to create a FAT32-formatted USB device:

  1. Open an elevated command prompt, then start the diskpart utility:

    diskpart.exe
  2. List all the disks and identify your USB stick:

    list disk
  3. Select the disk number that is your USB stick, e.g.,:

    select disk 4
  4. Remove all existing partitions:

    clean
  5. Create a new partition, make it active and format as FAT32, then assign a drive letter:

    create partition primary    select partition 1    active    format quick fs=fat32    assign
  6. Exit diskpart:

    exit

Example of Diskpart Output in Response to Commands Above

The final step is to copy all the files from the Windows install media to the USB device--for example, where d: is my ISO mount of Windows media and f: is my USB stick:
 

xcopy d:* f: /s /e

You can now boot your UEFI system and install Windows from this FAT32 USB drive. (See my FAQ about installing UEFI to a Windows machine.)
