Installing Unraid — USB Boot & Licensing Tiers

What You'll Need Before You Start

Gather these few things first. Having them ready means the whole process goes smoothly instead of stopping halfway to hunt for something.

That is really all. You do not need any special software beyond the free tool we download next, and you do not need to be a computer expert. You need patience and a cup of coffee.

• The server computer - the machine that will run Unraid, with its hard drives installed.
• A USB flash drive - 8 GB to 32 GB, from a trusted brand (more on picking one soon).
• A second, everyday computer - to download the tool and later open the server's web page.
• A keyboard and monitor for the server - just for the first boot and boot-menu step.
• Your home network - the server should be plugged into your router with a network cable.

Downloading the Official USB Creator Tool

To put Unraid onto a USB stick the easy way, you use a free program made by the Unraid team called the Unraid USB Creator. It does all the technical work for you.

Only download this tool from the official Unraid website. That way you know you are getting the real, safe program and the current version. There is also a manual method for advanced users, but the Creator tool is the friendly path and the one I recommend.

• Go to the official Unraid website (unraid.net) on your everyday computer.
• Look for the download or "Get Started" area and find the USB Creator tool.
• Download the version that matches your computer - Windows or Mac.

Picking the Right USB Stick

The USB stick is not just for setup - it stays plugged into your server and runs Unraid every day. So the stick matters more than you would think. Choose a good one.

One important detail: the stick must have a real, unique built-in ID number, called a GUID. Almost all name-brand sticks do. A few ultra-cheap ones do not, and those will not work with Unraid's license. Sticking with a known brand avoids this problem entirely.

Writing Unraid to the USB Stick

Now we use the Creator tool to put Unraid onto your chosen stick. The tool walks you through it, but here is the order so nothing surprises you.

The whole write takes only a few minutes. When it is finished, that little stick contains a complete operating system ready to run your server.

• Plug the USB stick into your everyday computer.
• Open the Unraid USB Creator tool you downloaded.
• Choose the newest Unraid version when the tool offers it.
• Select your USB stick from the list - double-check you picked the right drive.
• Give the tool permission to write, and wait for it to finish.
• When it says it is done, safely eject the stick.

Telling the Server to Boot From USB

A computer normally starts up from its internal drive. We need to tell your server to start from the USB stick instead. This is a one-time settings step.

Which key it is depends on your particular motherboard. The screen usually flashes a hint like "Press F12 for Boot Menu" for a second or two at startup. If you miss it, just restart and watch closely.

• The boot menu - as the server powers on, tapping a key (often F11, F12, F8, or Esc) brings up a menu where you pick the USB stick. Simplest option.
• The BIOS setup - tapping a key like Del or F2 at power-on opens the settings screen, where you can set the USB stick as the first boot device.

The First Boot

With the server set to boot from the USB, plug the stick into the server, connect a monitor and keyboard, and turn it on. You are about to see Unraid start up for the first time.

Write down or take a photo of that network address. That is the doorway to your server. You do the actual setup not on this black screen, but in a web browser on your other computer - which is our next step.

• A stream of text as Unraid loads - this is normal, not an error.
• After a moment, a login prompt on the screen.
• Most importantly, a line showing the server's network address (it starts with numbers like 192.168...).

Finding the Server in Your Web Browser

Unraid is controlled through a web page it hosts itself - like a private website that lives only on your network. To reach it, you use a browser on another computer.

If the page does not come up, double-check that the server and your computer are on the same network and that you typed the address correctly. A quick restart of the browser often helps too.

• Make sure your other computer is on the same home network as the server.
• Open a web browser (Chrome, Edge, Safari - any will do).
• In the address bar, type the network address you saw on the server screen.
• You can also try typing http://tower - "tower" is Unraid's default name.
• Press Enter, and the Unraid setup page should appear.

The Initial Web Setup Screen

The first time you open the Unraid web page, it greets you with a short setup. This is where your server gets its name and its first bit of housekeeping done.

Take your time here. There is no rush and nothing you do at this screen is permanent - you can change the name and password later from the settings. Read each screen before you click on.

• Naming your server (you can keep "Tower" or pick your own).
• Setting the password for the main account, called "root."
• A first look at the main screen, sometimes called the Dashboard.

Assigning Your Drives (Don't Start Yet)

Now Unraid shows you the hard drives it found inside the server. Here you tell it which drive does which job. Go slowly - this is an important step.

Assign each drive to its slot, but do NOT press Start on the array quite yet if you are still learning. Take a moment to be sure each drive is where you want it. Our separate guide on the array and parity explains these roles in full.

• Parity - a protective drive that lets you recover if a data drive dies. It must be as big as your largest data drive.
• Data drives - where your actual files live.
• Cache (optional) - usually an SSD that speeds up writing files.

The Free Trial and the License Tiers

Unraid lets you try everything free for a while before you pay. When you are ready, you buy a license. The license is a one-time purchase, not a monthly bill.

Unraid has offered a free trial you can extend a little, and paid tiers that differ mainly by how many drives (or "attached devices") they allow. The names and exact drive counts change over time, so check the current options on the official Unraid site when you buy.

Registering and Activating a License

When you decide to buy, activating your license is quick and happens right from the server's web page. The stick you already made is the key to it.

That is it - your server is licensed. Because the license is linked to the stick, you do not type in a long code every time. The stick itself is your proof of purchase.

• In the web page, find the registration or license area (often on the main Tools or Registration screen).
• Choose to purchase or activate a license.
• Follow the link to buy your chosen tier on the Unraid site.
• The license gets tied to your USB stick's unique ID automatically.
• Once activated, the web page shows your server as registered.

Why the Flash Drive's ID (GUID) Matters

Every good USB stick has a unique built-in serial number called a GUID. Unraid uses that number to lock your license to your specific stick. This is the single most important thing to understand about Unraid licensing.

Think of it like a house key cut to one specific lock. Your license fits only the stick with that exact ID. If the stick dies or is lost, the license link goes with it - though Unraid does offer a way to transfer a license to a new stick if yours fails, using the email you registered with.

• Treat the USB stick as valuable - it holds your license and your server's settings.
• Do not reformat it or use it for anything else.
• Make a backup copy of it (next page shows how).

Making a Backup Copy of the USB

Because everything important lives on that little stick, a backup copy is your safety net. Unraid makes this easy, and it takes just a minute.

This backup file holds your settings and, importantly, your license information. If your stick ever fails, this file plus a new stick gets you back up and running much faster. Make a fresh backup now and again whenever you change big settings.

• In the web page, click on the Flash device on the main screen.
• Look for a "Flash Backup" or download option.
• It saves a copy of the stick's contents as a single file to your computer.
• Keep that file somewhere safe - a cloud drive or another computer.

Naming Your Server

Your server needs a name so you and your devices can find it on the network. Unraid calls it "Tower" by default, but you can pick something friendlier.

Keep the name short, with no spaces or odd symbols - plain letters and numbers are safest. A clear name means you can later type it into a browser instead of remembering a string of numbers.

• Go to the Settings area of the web page.
• Find the network or identification settings.
• Change the name to something simple, like "HomeServer" or "BillsTower."
• Save, and the server will use the new name on your network.

Setting a Strong Root Password Right Away

The main account on Unraid is called "root," and it can change anything on your server. Give it a strong password immediately - this is your server's front door lock.

Do not leave the password blank and do not use something obvious like "password" or "1234." This one account controls your entire server and all your files, so it deserves a real password.

• During setup (or in Settings later), find the root password field.
• Choose a long password - a short phrase you can remember is great.
• Mix in a number or two; length matters more than fancy symbols.
• Write it down somewhere safe, like a password manager or a locked drawer.
• Save it, and use it every time you sign in to the web page.

A First Look at the Dashboard

Once you are signed in, the Dashboard is your server's home base. It shows you, at a glance, how everything is doing. Do not feel you must understand every number today.

Spend a few minutes just looking around. Clicking a tab to see what is there will not break anything. The more you poke around gently, the more comfortable it becomes.

• Your drives - listed with their health and how full they are.
• The array status - whether it is started and protected.
• System info - things like temperature and memory use.
• Tabs across the top - for Shares, Apps, Settings, and more.

Updating to the Latest Version

Software gets better and safer over time, and Unraid is no exception. Keeping it up to date means fewer problems and the newest features. The web page handles updates for you.

Before a big update, it is a good habit to make a fresh backup of your USB stick, just in case. Then let the update run and reboot when it asks. Most updates are quick and quiet.

• Unraid checks for updates on its own and shows a notice when one is ready.
• Look for an update or "OS update" option in the Tools or settings area.
• It downloads the update and asks you to reboot to finish.
• A reboot means the server restarts - your files are untouched.

Boot Troubleshooting Basics

If your server will not start from the USB, do not panic. The cause is almost always one of a few simple things. Run through this short list.

Work down the list one item at a time, restarting between tries. Most boot problems are a loose stick, the wrong boot choice, or a cheap USB stick. If you are still stuck, that is what I am here for.

• Is the stick fully plugged in? Try a different USB port, ideally one directly on the motherboard's back panel.
• Did the boot menu pick the stick? Restart and choose the USB stick again from the boot menu.
• Is the USB set first in the BIOS? Check that the stick is the first boot device.
• Did the stick get written correctly? If in doubt, write Unraid to it again with the Creator tool.
• Is the stick faulty? Rarely, a stick is bad - try a fresh, name-brand one.
