Supports LiveUSB persistence (preserving files across reboots; this feature is for Ubuntu only)
Multiple installs on the same device are not supported.
Hard drive install
This installation mode performs a network installation or "frugal install" without a CD, similar to that performed by the Win32-Loader.[4]
UNetbootin's distinguishing features are its support for a great variety of Linux distributions, its portability, its ability to load custom disk image (including ISO image) files, and its support for both Windows and Linux.[5] Unlike Wubi, and similar to the Win32-Loader, when installing to hard disk, UNetbootin installs to a partition, not a disk image, thus creating a dual-boot setup between Linux and Windows.[4][6]
Reception
A review in Full Circle in February 2021 stated, "despite the rather dated-looking interface, UNetbootin works perfectly, allowing the writing of almost any Linux or BSD distribution to a USB stick for testing or installation. It is a great example of the Unix philosophy: an application that does one thing and does it well."[7]
