You don't need any of this shit. Partition the drive as NTFS, mark the partition as active through Disk Management, and simply copy and paste the contents of the iso into the drive.
For maximum compatibility, just use FAT32 instead of NTFS. The official images will fit in a FAT32 volume. If you have a custom image that's more than the 4GB max file size of FAT32, and your device doesn't support ntfs or exfat, then you can use a single command to split the wim file into multiple chunks as explained here https://docs.microsoft.com/en-us/windows-hardware/manufactur...
