RufusとUEFI：NTFSの作成者はここにあります（これは、最新のWindows ISOに見られるような、4 GBを超えるファイルを含むイメージを起動するためにRufusが使用するものです）。

発生するエラーはUEFI：NTFSから発生し、次の2つの警告で説明できます。

1. [WARN] An NTFS service is already loaded means that your motherboard's UEFI firmware already provides an NTFS driver, and therefore the NTFS driver that Rufus would normally use can not be loaded because it would conflict with your firmware's own driver.
2. [FAIL] Could not open Root directory: [14] Not Found means that the UEFI NTFS driver provided by your motherboard is crippled, as it is unable to perform something as simple as opening the NTFS volume which is a standard file system operation that a proper UEFI file system driver should always be able to accomplish.

So you have 2 options here:

1. Contact your motherboard's manufacturer to let them know that the NTFS driver they include in their firmware is crippled and that they should update it with a better version (or remove it so that users can use a driver that actually works).
2. Try to use exFAT instead of NTFS as the file system in Rufus. Unfortunately that means you will first have to create a blank UEFI:NTFS drive (First click on Show advanced drive options to show the advanced options, then select UEFI:NTFS under Boot selection, then select exFAT as the file system and click START) and then manually extract the Windows Server 2016 files onto that disk, as Rufus will not do that for you (exFAT is not enabled by default for Windows images because not all versions of Windows work with it, and as a matter of fact, I don't even know if Windows Server 2016 is compatible with exFAT boot). Hopefully by using exFAT instead of NTFS, and provided Windows Server 2016 is compatible with exFAT boot the embedded NTFS driver from your motherboard should no longer be an issue and instead the exFAT driver provided by Rufus will be loaded, which should be able to open the volume without error. I can't promise that this option will work though...

ああ、お願いします、お願いします、エラーが発生した、使用しようとしたマザーボードのメーカーとモデルを提供してください。そうすれば、消費者は、不自由なNTFSドライバーを使用しているメーカーを見つけて、これらの製品に近づかないようにすることができます...
