WinUSB

WinUSB is a completely free program that allows you to create bootable media with the Windows operating system without prior formatting. It works with both physical DVDs and ISO images and automatically detects the version of the "operating system" after selecting the source. Windows 7, 8 (8.1) and 10 are supported.

In the start window of the program it is suggested to choose the medium on which to record. The connected USB drives are displayed in a convenient drop-down list, which also indicates the file system and the amount of free space. By the way, if you have enough free space on the external drive, you can write several versions of Windows to it at once (create a multi-boot drive). In this case, WinUSB will create a convenient menu with the help of which users will be able to choose the operating system to install when booting.

One main benefit of using WinUSB is creating bootable media with multiple Windows operating systems without formatting and with automatic version detection.

After you select the desired media and specify all recorded versions of Windows, the program will offer to start formatting. As we have already mentioned before, this step can be skipped by starting recording right away. If you do decide to format your drive, WinUSB will allow you to select one of the following file systems: NTFS, exFAT and FAT32.

That's how you can create a multiboot USB flash drive in just a few simple steps. For those who have problems finding the original Windows images, we recommend visiting the "Get Windows ISO" section. There you will find links to the latest operating system builds from Microsoft.
