In short:
  - Start an elevated command prompt:
  - Start diskpart and use it to:
    - List the disks.
    - Select the USB disk.
      - // In this example the USB disk is on disk 1, please check your output of list disk to determine which number the USB disk is on before proceding with select disk. //
    - Clean the USB disk.
    - Create one primary partition.
    - Format that partition with FAT32.
    - Mark the partition active (bootable).
    - Assign the USB disk a drive letter (K: in this example).
    - // The below commands assume the USB disk is disk 1, with the only other disk being 0 the OS disk. // <code>
diskpart
list disk
select disk 1
clean
create partition primary
format fs=FAT32 quick
active
assign letter=k
exit
</code>
  - Mount the Windows server 2016 DVD (i.e. double-click the ISO in explorer to have it mounted on for example D:\ as in this example).
  - Copy the contents of the ISO to the USB disk.
    - Skip install.wim as we need to split it to overcome the FAT32 max 4 GB per file limit.
    - Skip autorun.inf to prevent an on-access anti-virus scanner from interfering.<code>robocopy d:\ k:\ /E /XF install.wim /XF autorun.inf</code>
    - Split the install.wim in max 4 GB pieces and write those pieces to the USB disk:<code>dism /Split-Image /ImageFile:D:\sources\install.wim /SWMFile:k:\sources\install.swm /FileSize:4096</code>
