There is a certain kind of drawer we all have somewhere. It contains old USB sticks, mystery adapters, a cable we are scared to throw away, and at least one bootable Linux installer from five years ago. The label says “Ubuntu,” but nobody remembers which version. That drawer is exactly the sort of problem netboot.xyz is trying to solve.

At its simplest, netboot.xyz lets you boot operating system installers, live systems, and rescue tools over the network from one menu. Instead of downloading an ISO, writing it to a USB stick, booting from it, then doing the whole thing again next week for another system, you boot into netboot.xyz and pick what you need from a menu. It uses iPXE, which is a more flexible network boot system, to present that menu directly at boot time.

Think of it like walking into a diner instead of cooking everything from scratch. You turn on the machine, boot into the menu, and choose: Linux installer, live distro, rescue tool, utility, and so on. For people who install, test, repair, or rebuild machines often, this is a very nice shortcut.

Why It Is Useful

The old way is familiar but clumsy. You want to install Debian, Fedora, Arch, or another system, so you download an ISO. Then you flash it to a USB stick. Then you realise you used the wrong USB stick. Then the machine refuses to boot from it. Then next week you need another ISO and the whole dance starts again.

netboot.xyz removes a lot of that mess. The project’s own description says it is designed to boot many types of operating systems using lightweight tools, so you can evaluate, install, or rescue systems without constantly downloading and rewriting media.

That makes it especially handy for sysadmins, homelab users, repair shops, retro/modern hardware tinkerers, and anyone who regularly finds themselves saying, “I just need to boot this machine into something useful.”

What You Can Boot

The project supports a long list of operating systems and tools. On its GitHub page, the available systems include names such as AlmaLinux, Alpine, Arch Linux, Debian, Fedora, FreeBSD, Gentoo, Kali Linux, Linux Mint, OpenBSD, and many others. Windows is also listed, but with user-supplied media rather than being directly provided in the same way as many Linux and BSD options.

There are also utility options. The documentation mentions tools for things like disk cloning, drive wiping, and rescue work. That is where netboot.xyz becomes more than just an installer menu. It becomes the emergency toolbox you wish you had ready before the emergency happened.

How It Works in Practice

You can use netboot.xyz in a few ways. The quick route is to download one of its small bootloaders, such as an ISO or USB image, and boot from that. The bootloader then connects to netboot.xyz and loads the menu. There are bootloader options for legacy BIOS, UEFI, ARM64, and even Raspberry Pi 4 images.

Once the menu appears, you choose what you want to boot. For network installers, it usually loads the small installer kernel first, then the installer downloads only what it needs. For live systems, things can be heavier because live images are bigger, but netboot.xyz does work to make many of those images more iPXE-friendly.

In plain English: the tiny boot image gets the machine online, then netboot.xyz does the boring fetching and menu work for you.

You Can Also Self-Host It

For most casual users, the hosted version is enough. But the more interesting option for homelab and business use is self-hosting. netboot.xyz can be run in your own environment using Docker or Ansible, and the Docker version includes a web interface, NGINX for local assets, dnsmasq for TFTP services, and syslog for TFTP activity logs.

That matters because not everyone wants their boot process depending on the public internet. In a lab, office, workshop, or datacentre, local hosting can make boots faster and more controllable. You can also customise menus and add your own boot options without hacking the core project apart.

Who Is This For?

netboot.xyz is not something your auntie needs to install Chrome. It is for people who touch machines often.

It is for the person rebuilding laptops on a Saturday afternoon. It is for the sysadmin who has to rescue a server without hunting for an old ISO. It is for the homelab enthusiast who installs a different operating system every other weekend. It is for anyone who likes having options ready before something breaks.

It also has that wonderful “why didn’t I use this earlier?” feeling. The concept is simple, but the time saved adds up quickly.

The Catch

There is always a catch. You need a working network path. Some systems, network cards, firmware versions, or BIOS/UEFI setups can be annoying. Network booting is much better than it used to be, but it is still network booting. When it works, it feels magic. When it does not, you may still end up swearing at firmware menus.

Also, for live systems or bigger images, bandwidth matters. If you are booting over a slow connection, do not expect miracles. Self-hosting can help a lot here, especially if you regularly boot the same tools.

Final Thought

netboot.xyz is one of those projects that does not sound glamorous until you actually need it. Then suddenly it feels like the most sensible thing in the room.

It takes the chaos of bootable USB sticks, old ISOs, rescue disks, and installer images, and turns it into one clean network boot menu. For sysadmins, repair people, homelab users, and serial operating-system testers, it is a small tool that can save a surprising amount of time.

In short: keep one USB stick if you must. But let netboot.xyz carry the drawer.
