A Free Tool for Creating Bootable USB Flash Drives

The first thing you’ll need if you want to put one of these Linux distros on a USB flash drive. Rufus is a free tool that makes it easy to do just that.

We’ve discussed many options for making a bootable USB flash drive from an ISO file 10 Tools to Make a Bootable USB From an ISO File 10 Tools to Make a Bootable USB From an ISO File Installing an operating system from a USB drive is quick and portable. We test a few ISO to USB tools to find the best one for you. Read More . Use Rufus for most of these Linux distros. This is a free, very small, easy to use tool. (Another specialized tool is required for one of the distros, but more on that below.)

One useful tip: download the portable version of Rufus so you don’t have to install it on your PC. You can also keep it with your downloaded Linux ISO files in case you want to switch to a different Linux distro. Rufus is very fast at creating a bootable USB drive, enabling you to easily switch between different distros.

1. ArchBang

archbang linux operating system

ArchBang is based on Arch Linux and inspired by CrunchBang, which was another lightweight Linux distro. It’s is essentially Arch Linux made easier. It includes the power and flexibility of Arch Linux without the complex setup and installation.

ArchBang works on i686 or x86_64 compatible machines, uses 700MB of disk space, and requires 256MB of memory. It uses the OpenBox window manager

You can use ArchBang as a fully featured desktop operating system or as a portable, live OS. It’s fast, stable, and always up to date.

2. Damn Small Linux

damn small linux operating system

Damn Small Linux, or DSL, was designed to run graphical applications on older PC hardware. Think machines with early Pentium processors (such as the 486 series) and very little memory. It’s light enough to run with as little as 16MB of memory, and it can also be run fully in memory with as little as 128MB.

DSL started as an experiment to see how much software could fit into 50MB, but it eventually evolved into a full-fledged Linux distribution. It can be installed onto storage media with small capacities, like USB flash drives and memory cards, and onto a CD. You can also do a traditional installation onto a hard drive as a Debian desktop OS.

DSL includes a nearly complete desktop, and a very small core of command line tools. The applications available in DSL have been chosen for the best balance of functionality, size, and speed.

3. Elive

elive linux operating system

Elive is a lightweight Linux distro with its own custom desktop environment. It’s based on Debian and comes pre-installed with all the apps you need, including games.

If you’ve used a Mac before, you should be comfortable using Elive. It has a Mac-like dock and virtual desktops like Mac’s Spaces.

The desktop in Elive is a customized version of Enlightenment which offers a light and beautiful experience. It works well, even on very old PCs. The minimum requirements for Elive are a CPU speed of 300MHz, 700MB of disk space, and 128MB of memory.

When downloading Elive, select the IMG file. You’ll also need to download USBWriter to create a bootable USB flash drive or live CD.

4. Porteus

porteus linux operating system

Porteus is a lightweight, but complete, Linux distro that is optimized to run from a USB flash drive. Don’t have one? Don’t worry! Porteus will also work on an SD card, CD, DVD, hard drive, or other bootable storage media. It’s small and insanely fast, allowing you to boot and get online while other operating systems are still thinking about booting.

Porteus runs on any Intel, AMD, or VIA x86/64 processor, requiring only 512MB of disk space and 256MB of memory. No hard disk is required, as it can run from removable storage media. If you use Porteus on a removable storage media device, you can take advantage of its “Persistent” mode, which saves data directly on the storage device.

It is available in both 32-bit (perfect for older PCs) and 64-bit. A kiosk edition is also available, which is a minimal system that is locked down for use by the public on web terminals. You can choose to download the Cinnamon, KDE, MATE, or Xfce version of Porteus.

5. Puppy Linux

puppy linux operating system

Puppy Linux is a very lightweight Linux distro that should only be installed on and run from a USB flash drive, SD card, CD, DVD, hard drive, or other bootable storage media.

The minimum requirements include a 233MHz processor, 512MB free hard drive space (to create an optional save file), and 128MB of memory. The optional save file allows you to save your data directly on the removable media and run the system, with your saved data, on any computer.

There are two official variations you can download of Puppy Linux, Slackware-based and Ubuntu Tahr-based. Other unofficial versions, built by Puppy Linux enthusiasts, are available.

6. SliTaz

slitaz linux operating system

SliTaz, or Simple Light Incredible Temporary Autonomous Zone, is a lightweight, fully-featured, working graphical Linux distro that’s small, fast, stable, and easy to use.

The minimum hardware requirements include an i486 or x86 Intel-compatible processor, 80MB of disk space, and 192MB of memory (or as low as 16MB, depending on which version of SliTaz you use).

While SliTaz is running, you can use the removable media for other tasks or even eject it. The system runs in memory. SliTaz also has a “persistent” feature that allows you to store your data and personal settings directly on the removable media.

When the system is running you can eject the LiveCD and use your CD drive for other tasks. The Live system provides a fully-featured, working graphical distro and lets you keep your data and personal settings on persistent media.

7. wattOS

wattos linux operating system

WattOS is a lightweight, fully featured Linux distro based on Ubuntu that you can run from a USB flash drive, CD, or other removable media, run in kiosk mode, or install to a hard drive.

The minimum hardware requirements include any Intel or AMD processor, 700MB of disk space, and 192MB of memory for the Microwatt edition of wattOS (more if you use the LXDE edition).

The Microwatt edition is extremely lightweight and based on the i3 tiling window manager. It offers low resource requirements and simplicity. The LXDE edition is a lightweight, fully featured, and customizable desktop operating system that is great for beginners.

Note: When asked for a login in wattOS, enter “guest” as the user name and no password.

Revive Your Old Hardware With Linux

Bring your old PC or removable media back to life with any of these super small Linux distros. This could be a great way to provide a simple computer for a relative who doesn’t need all the bloat of a more complex operating system.

    A "7 Smallest Linux Distros" article , and you did not mention Tiny Core Linux?
    You should have sorted them by size.

          Hmm. A single link to 32-bit ISO won't download.

          The bittorrent alternative, and the 64-bit ISO, both work and download.

          A problem, but not one that would preclude inclusion of wattOS.

          Also, might be useful if you didn't call yourself "ADMIN" -- people might get the wrong idea.

    Who is the target audience for this article? Linux users? Windows users? Users switching to Linux from Windows?

    Where is antiX, Tiny Core Plus or Q4OS? Q4OS just released a new version based on the latest release of Debian 9 Stretch. This new version of Q4OS works on all systems going back to i386.

    There are 560 distributions in the DistroWatch database that are either dormant or discontinued that will run on old hardware. How "light" they are and how useful they are any more is the question one needs to ask themselves.

    According the the DistroWatch database neither DSL nor ArchBang have had any releases since 2012. I know DSL has been discontinued. What about ArchBang? Does anybody have any info on it?

      Obviously aimed at windows users as Rufus is not available for Linux & other tools need to be used (dd from the command line or unetbootin )

        I'll take your word for it. :-)

        The reason I asked is that, with the exception of Puppy, the above distros are not usually the ones recommended by 'experts' to Windows users. They are 'too different'. OTOH, for most Linux users these distros would not be the primary choice.

          I've played with both TinyCore and SliTaz before (in a VM environment). TinyCore has problems with basic mouse movement in a VM. But when all you want is the smallest distro out there, nothing beats TinyCore. The people behind Damn Small Linux are the authors of TinyCore. There was a falling out in the DSL community of which TinyCore was the result, which explains why DSL is "dead" and TinyCore is still doing well. TinyCore is NOT for the feint of heart. Even if you think you are a hardcore Linux person, you've not come even close. There are so many quirks with TinyCore that I lost count. However, if you are building embedded hardware, TinyCore is awesome because all the other distros requires hundreds of MB to GB of storage. TinyCore also fully boots into RAM in under 5 seconds on the crappiest of hardware specs.

          SliTaz is the next smallest and really the only small distro that's usable by the average Linux person. It also has a respectable package manager that isn't based on the usual suspects (pretty sure they made their own custom package manager). SliTaz has a longer boot time than TinyCore but is also really fast (15 second boot times).

          Everything else out there is based on Debian, RedHat, Arch, or Slackware and have user experiences similar to the big, bloaty distros that sit on top of those (e.g. Ubuntu) that require 500MHz CPU + gobs of RAM + GB of disk. There's nothing particularly wrong with those but I'd like to see more non-traditional ultra-tiny distros pop up. People claim "choice" but when I want ultra-tiny, then there are only two active distros to pick from and one of those is of limited capability. That's not really much of a choice.

    Just thought I'd make mention of "Lightning Linux" and "LxLE"....two distros based on Ubuntu but uber-fast and light. One runs the OpenBox desktop environment and is quite pleasing to the eye. While being light on resources, and still can handle things like CodeBlocks, Ninja-IDE and Eclipse Programming IDE's. The other is running the LXDE desktop and also is ablt to handle things like web browser videos, downloads, and watching hi-def movies in VLC without breaking a sweat. Just thought I'd throw hat out there....great article! Awesome information to have!

      Not to mention, DSL hasn't been updated in like 6 years. It still runs a 2.4 kernel which flat-out *will not work* with anything newer than about a Core 2.

        Christ, you people think EVERYTHING should run on brand-new hardware.

        That's the whole POINT of these tiny distros.....that they rejuvenate OLD hardware. And there's still a LOT of that around.

        • dragonmouth
          October 11, 2017 at 1:04 pm

          It's not a question of OLD hardware. It's a question of OLD software. Would you run Win98/Me or Win XP if you had the hardware? I still have the i486DX4 PC that i built. It has Win 3.11 WFW installed on it. Yeah, it works but only in stand alone mode and only with applications of that vintage. It's not very useful.

          DSL has been DISCONTINUED. That means no one is working on it any more. It's last production release was in 2008. The last alpha release was in June of 2012. So no security updates have been released for DSL in at least 5 years. Since the last release of DSL of any kind, there have a few major security problems with components used in Linux distros. Do you, perhaps, recall something called "Heartbleed"? DSL certainly hasn't been patched for it. Would you want to use an O/S that full of security holes, even if it "rejuvenates" your old hardware?
