Installing Windows 10 Pro from a USB isn’t exactly rocket science, but it can get a little confusing if you’re not familiar with the process or run into hiccups. Sometimes, the USB doesn’t boot properly, or the setup stalls unexpectedly. Basically, if your PC won’t recognize the USB or if you’re trying to do a clean install on a machine that’s acting weird, this guide is here to help. The goal is to walk you through the steps—covering what to prepare, how to create a bootable drive, and tips to troubleshoot common issues. Because of course, Windows has to make it harder than necessary sometimes. By the end, you should have Windows 10 Pro installed and running smoothly, saving yourself a few headaches along the way.
How to Install Windows 10 Pro from USB
Preparing the USB Drive Properly
First things first: the USB needs to be formatted correctly. Use a drive with at least 8GB of storage; anything less and you’re out of luck. Format it to FAT32. Yeah, FAT32 is kinda old-school, but it’s still the most compatible for booting. To format it, you can just plug it in, open This PC, right-click the USB drive, select Format, choose FAT32, and hit Start. On some setups, this fails the first time, then suddenly works after a reboot or when you try again. Because Windows likes to be stubborn like that.
Downloading the Windows 10 Pro Media Creation Tool
Next, grab the official Microsoft Windows Media Creation Tool. It’s pretty straightforward, but make sure you’re downloading from the real Microsoft site, or weird things could happen. Launch the tool once downloaded, and it’ll ask if you want to upgrade or create installation media. You want to choose Create installation media for another PC. This helps you create a bootable USB disk ready to go, rather than an ISO file that’s just sitting there gathering dust.
Making the USB Bootable with the Right Files
When you run the Media Creation Tool, pick the correct language, edition (Windows 10 Pro), and architecture (x64 is common).Then, select the USB drive from the list. This is the part where the tool copies all those Windows files onto your USB and makes it bootable. Do not interrupt this process—it’s crucial that everything completes successfully. Sometimes, the process feels slow and the progress bar stalls, but just be patient. In my experience, the first attempt might fail due to a bad USB or something lurking in the background, so don’t be surprised if you have to redo it once or twice.
Booting from the USB and Installing Windows
Now for the tricky part—getting your PC to boot from the USB. Restart your machine and immediately press the key to access the Boot Menu or BIOS. Common keys are F2, F12, Delete, or Esc. On some machines, you have to disable Secure Boot or change Boot Priority to USB device. Check your motherboard or laptop manual if you get stuck—because each BIOS is a little different. Once it boots from the USB, the Windows setup should kick in. Follow the prompts: choose language, time, keyboard layout, and click Install Now. You’ll be asked for a product key, which you can skip if you’re reinstalling or planning to activate later. Just know that if you skip it, Windows will be in a notice mode until activated. During setup, you can also delete old partitions or format your drive if starting fresh.
Troubleshooting Common Boot Issues
So, what if the PC just doesn’t see the USB at all? That’s annoying, but potential fixes include:
- Double-check BIOS settings—make sure Secure Boot is disabled and Fast Boot isn’t interfering.
- Rearrange boot order to prioritize USB devices.
- Try recreating the bootable USB from scratch. Sometimes, the image isn’t properly written, especially if the USB was low quality.
- Check if your USB port is working. Weird, but some laptops/boards have quirks—prefer a port directly on the motherboard, not a hub.
Not sure why it works sometimes, but on some systems, you need to enable legacy boot mode or disable UEFI restrictions. Whatever tweaks you do, be ready for some trial and error.
Tips for Better Success During Installation
- Back up important files first — because installing a fresh OS can wipe them out if you’re not careful.
- Keep your product key nearby, especially if you have a legit license. Otherwise, you might end up needing to activate later.
- If the setup hangs or errors out, check your BIOS settings for Secure Boot or UEFI options. Sometimes enabling/disabling these makes a difference.
- Expect the process to take anywhere from 20 minutes to over an hour depending on hardware. Just be patient and don’t shut down midway.
Frequently Asked Questions
Do I need an internet connection to install Windows 10 Pro from USB?
Not necessarily, but it helps. You can install Windows offline, but after install, Windows will want to grab updates and drivers, which is easier with internet.
Can I reuse the same USB for multiple installations?
Yep, just delete the Windows files and re-run the Media Creation Tool if needed. But beware, if you’re switching versions or editions, you might need a new ISO.
How long does the installation usually take?
Depends on your hardware, but most stay around 20-60 minutes. Faster SSDs cut the time down a lot.
Installing without a product key?
You can install without it, but Windows will be in a limited mode until you activate with a real key. Works fine for testing, though.
Will this wipe my files?
If doing a clean install (delete partitions and format), yes — everything on that drive will go poof. Backup important stuff before starting.
Summary
- Format the USB using FAT32.

Wrap-up
Getting Windows 10 Pro on a USB and onto your PC isn’t as bad as it seems once you understand the steps. Sometimes, hardware or BIOS quirks make it annoying, but a little patience and troubleshooting go a long way. Once installed, it feels good to have a fresh start or upgrade—plus, you get to mess around with all the new features. Hopefully, this saves some time and hassle for someone out there. Fingers crossed this helps and happy upgrading!
