SARDU MultiBoot Creator vs UNetbootin

SARDU MultiBoot Creator builds bootable media for computer maintenance from a catalog of more than 300 ISO images, organized into Antivirus, Utility, Linux, and Windows categories. It can create a multiboot rescue disk on a USB flash drive or DVD, and its downloader can fetch selected images and build a USB drive in one step. The resulting media can support Windows installation, cloning, backup and restore, data recovery, password recovery or change, RAM testing, and hard disk checks. SARDU is portable: unzip the download and run it without installation. Version 6.1.0 is offered for Windows and 4.4.0 for GNU Linux. Free licenses are for personal, non-commercial use; PRO licenses permit commercial use. PRO includes BIOS Legacy and UEFI boot support, while free licenses do not include the stated PRO UEFI feature. Secure Boot must be disabled for the described Windows installation workflow. SARDU offers free plans and paid options from €11.90. Support is available through an FAQ and by email in Italian or English.

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.
