[ntfs] fix creation of Windows 7 bootable USB from XP

Browse source 
* When using Win7 installation ISOs, XP would return the error:
  [0x00000456] The media in the drive may have changed
* This seems to be due to unmounting of the drive before writing
  the PBR
* Also, our ms-sys/NTFS code wasn't identifying NTFS properly on XP
