  1. Insert a USB key in the system.
  2. Open a command prompt.
  3. Use diskpart.exe to format the USB key as a single FAT32 partition spanning the entire key, and set the partition to active, as shown in this example.
    • diskpart
    • list disk (note what disk the USB drive is. In this example it is Disk 2…I)
    • select disk 2
    • clean
    • create partition primary
    • select partition 1
    • active
    • format fs=fat32 quick
    • assign
    • exit
    • Copy files from ISO to the USB key.

For NTFS bootable USB drives there are some additional steps.

  1. Follow the steps above, but when formatting use format fs=ntfs quick.
  2. Remount the USB key if diskpart ejects it.
  3. Insert a Windows Operating System installer ISO image.
  4. Open a command prompt as Administrator and navigate to the boot folder (mine ISO is mounted in J:) J:\boot>
  5. bootsect /nt60 G: (where G: is the drive letter of your USB key). You should see something like this:
    J:\boot>bootsect.exe /nt60 G:
    Target volumes will be updated with BOOTMGR compatible bootcode.

    G: (\\?\Volume{db89f4a5-faa0-11e4-825a-989096b10a0c})

    Successfully updated NTFS filesystem bootcode.

    Bootcode was successfully updated on all targeted volumes.
