How to Install Windows 11 Pro from USB: A Step-by-Step Guide

How to Install Windows 11 Pro from USB

Installing Windows 11 Pro from a USB isn’t exactly a walk in the park, but it’s not too tricky either — more like navigating a maze, really. Once you get the hang of it, it feels pretty ace. Basically, you turn a USB stick into a magic wand that brings Windows 11 straight to your desk. Here’s the lowdown on how to do it without going troppo into the technical stuff.

Create a Bootable USB Drive

First up, grab yourself a USB drive — at least 8 GB or bigger. Head over to Microsoft’s website to download the Windows 11 Pro ISO; steer clear of dodgy sites, no one wants a virus to crash their party. Once you’ve got your ISO, a handy tool like Rufus makes it a piece of piss. It’s basically a “click, sit back, and let it do its thing” kinda deal. Plug in your USB, select the ISO, and let Rufus take care of the rest. Make sure your USB has at least 8 GB of storage — Windows really likes to stretch out.

Feeling a bit more adventurous? You can also whip up a bootable USB using the command line with DiskPart. Here’s how you do it:

Open Command Prompt as Admin.
Type diskpart and hit Enter.
Run list disk to see all your drives, then find your USB.
Choose it with select disk X (replace X with your USB number).
Clean the drive with clean.
Create a new partition: create partition primary.
Quick-format it: format fs=ntfs quick.
Assign a drive letter: assign.
Type exit to close DiskPart.

Rufus makes this whole job easier, but if you hit snags, DiskPart might save the day.

Plug the USB into Your PC

Once you’ve got a bootable USB, slot it into your PC — ideally into a port on the back (like, one directly on the motherboard). Those front ports can be a bit dodgy for booting. The key is making sure your BIOS/UEFI can see the USB when you turn the machine on.

Restart and Boot from USB

This is the fun part! Restart your PC and press the key to get into the boot menu (usually F12, F2, Del, or Esc). It’s a bit like playing a game — the keys can change depending on your machine. For an extra leg up:

Go into BIOS/UEFI (usually Del, F2, or Esc).
Find the Boot menu.
Set your USB as the first boot option.
Disable Secure Boot if it throws a wobbly.
If the USB doesn’t show up, check if Legacy Boot is enabled.
Save your settings and reboot.

If all goes well, you’ll see the Windows setup screen flash up. Easy as!

Follow the On-Screen Instructions

This part is pretty straightforward — like following a good ol’ recipe, but no cooking involved. Pick your language, region, Keyboard layout, and all that jazz. You can choose to upgrade or do a fresh install — if you want a clean slate, pick the clean install. Windows will go through its pre-install dance, which might take a bit. Just be patient and don’t fret if it restarts a few times. It’s normal.

Finish the Installation

Soon enough, you’ll be saying g’bye to the setup wizard and greeting your shiny new OS. You’ll need your product key, which is handy to have — if you don’t have it on hand, no worries, you can activate later. During the install, connect to Wi-Fi to grab updates and activate your copy:

Click the Wi-Fi icon on the setup screen or plug in an Ethernet cable.

If activation is playing hard to get at first, don’t stress. You can sort it out later in Settings > Update & Security > Activation.

Also, Windows will ask if you want to sign in with a Microsoft account or stay with a local account. Many folks stick with local for privacy, but some like the syncing perks of a Microsoft account. Your call!

While Windows sorts itself out, there might be a progress bar or spinner going for a bit — anywhere from 20 minutes to an hour, depending on your system. Just hang in there, mate.

And there it is — your new Windows 11 Pro desktop, looking fresh as a daisy. Now, it’s time to install your favourite apps or just sit back and enjoy the new look.

Pro Tips for Installing Windows 11 Pro from USB

Back up anything important before you start. This process wipes your drive, so best be safe.
Downloading the ISO from Microsoft’s site is the way to go — no mucking about.
Double-check if your PC ticks all the minimum specs — TPM 2.0 and Secure Boot are must-haves. To check TPM:

Run tpm.msc via Run (Windows + R) to see if TPM is sorted.

Jump into your BIOS/UEFI to see if Secure Boot is turned on.
Keep your product key handy — it’ll save you heaps of time later.
If you get stuck, there’s plenty of friendly online forums where others have been through it before.

FAQs

What do I need to create a bootable USB drive?

Just an 8 GB USB and the Windows 11 ISO. Rufus makes it a doddle. Or you can use the Media Creation Tool from Microsoft:

Download the Media Creation Tool from Microsoft.
Run it, and choose Create installation media (USB flash drive, DVD, or ISO file).

Can I use the same USB for multiple installs?

Absolutely — just make sure not to delete the setup files, and it’ll be good to go for heaps of installs.

What if my PC doesn’t pick up the USB?

Try plugging it into another PC; if it boots there, your USB’s fine.

Not strictly, but being online makes it easier for Windows to grab updates and activate smoothly. Better to be plugged in, really.
