OpenSolaris is an operating system developed by Sun Microsystems. It works well on desktops, laptops, servers and data centers. OpenSolaris is based on the graphical interface like Ubuntu and has a rich graphical desktop and a window for easy navigation. It is now available in version 11 and can be downloaded free of charge from the Oracle website.

OpenSolaris Features

      • ZFS (the file system)
      • Bootable clones
      • Data checksum
      • Storage pools (zpools)
      • Snapshots (using the Copy function) on Write)
      • Timers

In addition, Sun’s ZFS file system now features native Solid State Drive (SSD) management technology, enabling system administrators to optimize SSD performance.

ReactOS

This is a free Windows compatible operating system that offers the advantages of running native Windows applications. In addition to being open source software (its strong point), the tool has a really cool feature that Windows does not offer – an application manager that is very similar to the Linux package manager. To use the software, go to the official React OS website and after downloading the image, use a tool like Rufus to write it on a USB stick.

Haiku OS

What most users like about this operating system is its consistency and coherence. To boot the operating system, simply insert the USB stick into a USB port and reboot. This should not be a problem, as most modern computers today can be configured to boot from the USB stick. The operating system is fast and responsive. It is also preinstalled with a number of applications and demos. Start-up should therefore not pose any problems for new users either.

Fedora & Debian are the other distributions that should be mentioned here.
