The fact that you get the warning An NTFS service is already loaded indicates that the UEFI firmware advertises that it already has an NTFS driver, and therefore that the one that UEFI:NTFS (which is the custom UEFI bootloader that Rufus installs to boot from NTFS partitions) should not be necessary.
As a result, because you can't have 2 separate drivers (the one from the ASUS UEFI firmware and the one from Rufus) installed for the same purpose (providing access to NTFS volumes), the UEFI:NTFS bootloader attempts to use the ASUS advertised one to boot.
However, it seems that this driver, which should be able to handle the generic calls issued by UEFI:NTFS to locate and launch the Windows bootloader residing on the NTFS partition, doesn't play nice and returns a mapping error...
Now, if you are lucky, the above means that when you are trying to boot your Windows USB drive, you should see 2 entries for UEFI boot of that device: One for the UEFI:NTFS bootloader (that resides on the second small FAT partition that Rufus created on the drive, and which is the one that produces the messages above) and one for the Windows bootloader that resides on the primary NTFS partition. If that is the case, you should try the other bootloader, as, if Asus didn't screw up their NTFS driver, it should allow you to boot Windows without using the UEFI:NTFS workaround.
One the other hand, if you only see one entry for the UEFI boot of your USB drive, then it means that Asus screwed up their driver, as it means that, as far as UEFI applications are concerned, they do advertise that an NTFS driver is available to access NTFS partitions, yet, if that driver cannot be used to enumerate the Windows native bootloader (which is what should produce the second UEFI boot entry for your USB drive), or to allow UEFI applications to access NTFS files, then it means that their driver is broken.
So, do you see two boot entries for the USB drive or not? And if you see two, what happens when you select the other one?
