In this step you have to download a rather old version of Windows 10. All the data on the USB drive will be lost in the process, so make sure to save the data elsewhere before you continue. You need a USB stick with a capacity of 8 GB or more. The instructions are absolutely foolproof, no terminal is required and the resulting USB drive can be used to install Windows on any machine and is not limited to “Boot Camp”. The current version of ImageUSB is v (2449 KB).This tutorial explains how to create a bootable Windows USB in macOS without any additional tools. In this scenario, users will need to reformat the UFD in order to access the rest of the storage space. For example, if a 2GB image is copied to an 8GB USB Flash Drive, the drive will only be able to use two out of the eight gigabytes of storage space. Warning: Due to the forensic nature of image duplication by ImageUSB, please ensure that you select UFDs with a storage size similar to the image you wish to duplicate. As of V1.5, imageUSB now supports extraction of ISO contents onto USB Drive. A reformat can recover the drive however. So the direct imaging of ISO9660, Joliet or UDF file system, from a CD, to a USB drive, might not allow the USB drive to function in all operating systems.

(*) CD ISO images use a different file systems compared to USB drives. In addition, imageUSB has the ability to reformat even hard to format drives and reclaim any disk space that may be lost previously. Or alternatively to just Zero the MBR and/or GPT entries that exists on the drive. This will replace the contents of the entire drive with 0s. ImageUSB includes functionality to Zero a USB Flash Drive. ImageUSB can perform flawless mass duplications of all UFD images, including bootable UFDs. Unlike other USB duplication tools, ImageUSB can preserve all unused and slack space during the cloning process, including the Master Boot Record (MBR). ImageUSB can also be used to install OSFClone to a USB Drive for use with PassMark OSForensics™. ImageUSB also supports writing of an ISO file byte by byte directly to an USB drive (*).

Capable of creating exact bit-level copies of USB Flash Drive (UFDs), ImageUSB is an extremely effective tool for the mass duplication of UFDs. ImageUSB is a free utility which lets you write an image concurrently to multiple USB Flash Drives.
