Windows 10 / 8 / 7 comes with an inbuilt feature to burn ISO files on CD / DVD. But, there is no direct way to burn USB Flash Drive to make it bootable. One can use Microsoft’s Windows USB/DVD Download Tool or third-party ISO2Disc freeware to create a bootable USB flash drive. Windows USB/DVD Download Tool comes with limited functionality, which means you can only create a bootable USB flash drive of Windows 7 / 8 / 10, but ISO2Disc also lets you create Windows To Go Drive. The Windows To Go feature lets you mount Windows 10 without actually installing OS on any computer.
A WinUSB Maker is a freeware tool that lets you create a bootable Windows startup disk on any removable USB thumb drive or USB hard drive. Apart from creating a bootable USB drive, this tool also creates bootable ISO images, GRLDR, DOS disks, and full drive backup/restore. It is effortless to use. You need a Windows installation disk or an existing setup disk, ISO image, or folder to use the program.
WinUSB Maker also includes checkboxes to force either NTFS or FAT32 file systems, expanding the range of compatible devices. It also verifies the valid bootable ISO file.
