In their own words
FlashBoot
FlashBoot is a Windows utility for preparing Windows installations on internal drives or USB storage, moving Windows to another computer, and creating portable computer copies. The maker lists workflows for Windows 7, 8.x, 10, and 11, with availability depending on edition. FlashBoot Free converts Windows setup media for USB, installs Windows 8.x, 10, or 11 as a full operating system on USB, and saves, restores, or copies USB images while retaining bootability. Pro adds Windows privacy controls, operating-system cloning, and driver integration. Its privacy options include registry tweaks and a DNS proxy for blocking selected Windows network activity; it can also set up Windows 11 without an online account. Pro supports installable clones with apps and data, bootable USB clones, and selected driver integration. For full Windows on USB, USB 2.0 is the minimum, 3.0 is recommended, and at least 16 GB is specified. FlashBoot does not require activation or network access during operation.
UNetbootin
UNetbootin creates bootable Live USB drives for Ubuntu and other Linux distributions, allowing installation without burning a CD. It can download a supported distribution or use a Linux ISO already on the computer, and the listed targets are a USB drive or hard disk. Built-in downloads include Ubuntu, Debian, Fedora, Arch Linux, Linux Mint, and FreeBSD, as well as system utilities such as Parted Magic and SystemRescueCD. The site says most Linux ISO files should work, though some require extra boot options or changes, and some cannot boot from USB as-is. Non-Linux operating system ISOs should not be expected to work because they use a different boot mechanism. UNetbootin is available for Linux, macOS, and Windows, and is free; donations are accepted. The source code is available on GitHub under GNU GPL Version 2 or above. Linux download options include an Ubuntu PPA, 32-bit and 64-bit binaries, packages for several distributions, and source code.
