FlashBoot: Free and Paid-for Portable Boot Drive for Windows OS
With FlashBoot, you can carry a fully-functional copy of Windows 8.1 or Windows 10 in your pocket, stored within a flash drive. The Free version of the software offers the ability to create a fresh, bootable copy of Windows on a USB, whilst the Pro version clones your existing Windows installation, complete with documents, applications, settings, and more.
FlashBoot is useful for preparing a fresh install of Windows, whether that be for a new computer that you're purchasing, or a customer computer under your care that requires a full reinstall. However, the Pro version is perfect for creating a clone of your existing setup, so that you can move from your old to your new machine without any lost settings, data, or apps.
