  Disk Management

  Why it's wrong here

  Disk Management is an MMC snap-in for managing physical disks and volumes. It can initialize a USB drive, create a partition, format it with FAT32 or NTFS, mark it active, and assign a drive letter. However, it provides no mechanism to extract the contents of a Windows 10 ISO, write a master boot record or GPT boot structures, or place the Windows setup files (bootmgr, boot.wim, install.wim) that must be present on a bootable installation drive. It operates only on the disk layout, not on the file-level installation environment required for bootable media.

  Windows Media Creation Tool

  Why this is correct

  The Windows Media Creation Tool is Microsoft's official utility for producing installation media from a Windows 10 ISO. It automatically extracts the ISO contents, deploys the boot-critical files (bootmgr, EFI/Microsoft/Boot, boot.wim, install.wim), and configures the USB drive's partition scheme and boot sector for both UEFI and legacy BIOS systems. It also validates the downloaded files and can create media with the current feature update, or directly use an existing ISO file. This one-stop process makes it the correct and most straightforward choice.

• ✗

  File Explorer

  Why it's wrong here

  File Explorer can mount an ISO as a virtual DVD drive or copy its files to a USB stick, but moving files alone does not make a flash drive bootable. A bootable Windows USB requires an active primary partition, a valid master boot record (or GPT protective/boot structures on UEFI), and a boot loader such as bootmgr with a BCD store — none of which are installed by a plain file copy. At best, File Explorer will leave you with a data drive that firmware cannot recognize as a boot device.

• ✗

  Diskpart

  Why it's wrong here

  Diskpart is a command-line utility for disk management: it can clean a drive, create a primary partition, format it, assign a letter, and mark the partition active. While these are necessary preparatory steps, Diskpart itself cannot pull files from a Windows 10 ISO, extract the Windows setup boot environment, or generate the boot sector; you would still need additional commands like `bootsect /nt60` and `bcdboot`, plus manual ISO extraction. It is a partial tool, not a complete solution, and is far less reliable and more error-prone for novices than the Media Creation Tool.
