Bootable USB Drive helps quickly format any USB flash drive, USB thumb drive, and USB pen drive and load the Windows OS.
Loading an OS can be a lengthy procedure, and compared to other tools, Bootable USB Drive is pretty fast. Also, if you encounter a corrupted MBR (Master Boot Record) in the first sector of a USB drive, Bootable USB Drive can quickly fix it. This option requires you to enable the Update MBR option.
Bootable USB Drive will allow you to create a bootable USB drive out of a USB drive that is heavily loaded with data. For example, suppose the USB flash drive capacity is 32GB. The existing data already takes up 24GB of storage space; you can still use the USB drive to create a bootable USB drive for Windows installation/reinstallation without erasing any data on the USB drive. No format operation will be performed before creating the bootable USB drive. When the USB drive is selected at startup, it will immediately boot into the Windows installation.
With a bootable Windows USB stick, you can install, reinstall, or upgrade Windows, repair/fix a broken configuration, test out the Windows desktop experience, and boot into Windows from an internet cafe or on a borrowed machine.
Rufus is a small Open Source utility that helps quickly format and creates bootable USB flash drives, such as USB keys/pen drives, memory sticks, etc. Rufus is now integrated with Fido to download Windows 10 and 8.1 ISOs from Microsoft servers. Video guide available.
WinToUSB will install and run the Windows operating system on a USB hard drive or USB flash drive, using an ISO image or CD/DVD drive as the installation source.
