What you need before you start
Resetting your PC with a USB drive requires three things: a USB drive with at least 8 GB of storage space, a working computer (yours or someone else's), and the Windows installation files. You will use the working computer to create a bootable USB drive, then plug that drive into the PC you want to reset and restart from it.
Before you begin, back up any files you want to keep. A reset wipes your drive clean — you will lose documents, photos, programs, and settings. If your PC still turns on, copy important files to an external drive or cloud storage first. If it will not start at all, you cannot recover files this way, so consider whether data recovery is worth exploring before you reset.
You will also need to know your Windows version (Windows 10 or Windows 11) and whether your PC uses a 32-bit or 64-bit system. You can find this on a working PC by opening Settings, selecting System, then About. Write down the version and system type before you start.
Key Takeaways
- You need a USB drive with at least 8 GB of space and a second working computer to create the bootable installation media.
- read the Windows installation tool from Microsoft's website and follow the on-screen steps to prepare your USB drive.
- Insert the USB drive into the PC you want to reset, restart the computer, and press the boot key (usually F12, Esc, or Del) to boot from the USB.
- During setup, choose the option to do a clean install, select your drive, and let Windows install — this erases everything and installs a fresh copy of Windows.
- After installation completes, you will need to reinstall your programs and restore your backed-up files from external storage.
Creating a bootable USB drive on a working computer
Go to Microsoft's website and read the Windows installation media creation tool for your version of Windows. For Windows 10, search for "Windows 10 read" on Microsoft.com and look for the Media Creation Tool. For Windows 11, search for "Windows 11 read" and find the same tool. Save the file to your desktop.
Plug your USB drive into the working computer. Open the Media Creation Tool you just downloaded. Select "Create installation media for another PC," then choose your language, Windows version, and system architecture (32-bit or 64-bit — match what you wrote down from your PC). When prompted, select your USB drive from the list and click Next. The tool will read Windows files and write them to your USB drive. This takes 10 to 20 minutes depending on your internet speed.
When the process finishes, safely eject the USB drive. Do not unplug it while the tool is still running — wait for a message saying the drive is ready to use.
Inserting the USB drive and accessing the boot menu
Plug the USB drive into a port on the PC you want to reset. Restart the computer completely — if it is off, turn it on; if it is on, shut it down fully and then power it back on. Do not use sleep mode or restart; do a full shutdown.
As soon as the computer starts, begin pressing the boot menu key repeatedly. The key varies by manufacturer: common ones are F12, Esc, F2, F10, or Del. You will see a brief splash screen with the manufacturer's logo — that is when to press. If you miss the window, the PC will boot normally into Windows. If that happens, shut down and try again, pressing the key faster.
A menu will appear listing boot options. Look for an entry that includes your USB drive's name or says "USB Device" or "Removable Media." Select it and press Enter. The computer will boot from the USB drive, and the Windows setup screen will appear within a minute or two.
Running Windows setup and choosing a clean install
The Windows setup wizard will ask for your language, time zone, and keyboard layout. Select your preferences and click Next. On the next screen, click "Install Now." You will be asked to enter a Windows product key — if you have one, enter it. If you do not have a key, you can skip this step and enter it later after installation.
Read the license terms and check the box to accept them. Click Next. On the screen asking which type of installation you want, select "Custom: Install Windows only (advanced)." This is the option that performs a clean install and erases your drive.
The next screen shows your hard drives and partitions. Select the main drive (usually labeled as the largest drive or listed as "Drive 0"). Click Next. Windows will warn you that everything on this drive will be deleted — this is expected. Click OK to proceed.
Waiting for installation and first startup
Windows will now install. This process takes 15 to 30 minutes. Your PC will restart several times — do not turn it off or unplug it. Leave the USB drive plugged in until installation is completely finished and you see the Windows login screen.
Once you reach the login screen, remove the USB drive. Windows will ask you to set up your account, choose privacy settings, and connect to the internet. Follow the on-screen prompts. You now have a fresh copy of Windows with no programs, files, or user data from before.
Reinstalling programs and restoring your files
After setup finishes, your PC will look empty. You will need to reinstall the programs you use. Go to Microsoft Store or the websites of the software you need (Chrome, Firefox, Office, Zoom, etc.) and read them one at a time. Install each program normally.
If you backed up files to an external drive or cloud storage before the reset, connect that drive or sign into your cloud account and copy your files back to your PC. If you used OneDrive, Google Drive, or another cloud service, sign in and your files will sync automatically.
You may also need to reinstall drivers for printers, graphics cards, or other hardware. Windows will install many drivers automatically, but some devices may need manual installation. Check the manufacturer's website if a device is not working.
Troubleshooting common problems
If the boot menu does not appear, you may be pressing the wrong key. Restart and try a different key from the list above. If none work, look up your PC's manufacturer and model number online — most manufacturers publish which key to use. You can also try holding the key down continuously as the PC starts rather than pressing it repeatedly.
If Windows setup starts but fails partway through, the USB drive may be corrupted. Go back to the working computer, rerun the Media Creation Tool, and create the USB drive again. Make sure you select the correct USB drive — selecting the wrong one will erase that drive instead.
If your PC has a very old hard drive or solid-state drive, it may fail during installation. If setup repeatedly stops at the same point, the drive itself may be failing. In that case, you may need to replace the drive before you can install Windows.
Frequently Asked Questions
Do I lose everything when I reset my PC with a USB?
Yes. A clean install erases your entire drive, including all programs, files, settings, and user accounts. This is why backing up important files before you start is essential. If you have files you cannot afford to lose and your PC will not start, consider consulting a data recovery service before attempting a reset.
Can I use the same USB drive to reset multiple PCs?
Yes. Once you create a bootable USB drive with the Windows installation files, you can use it on any PC with the same Windows version and system architecture (32-bit or 64-bit). You do not need to recreate it for each PC.
What if my PC does not have a USB port?
Most PCs have USB ports on the back or sides. If yours does not, or if the ports are not working, you may need a USB hub or adapter. Alternatively, you can create a bootable DVD instead of a USB drive using the same Media Creation Tool on a working computer with a DVD drive.
Do I need a product key to install Windows from USB?
You can install Windows without entering a product key during setup — just skip that step. Windows will ask you to enter a key later. If you do not have a key, Windows will still work but may show a watermark and have some features restricted. You can purchase a key from Microsoft or use a key from a previous Windows installation if you have one.
How long does a full PC reset take?
Creating the USB drive takes 10 to 20 minutes. The actual Windows installation takes 15 to 30 minutes. Reinstalling your programs and files afterward can take hours depending on how much software you use and how large your file backups are. Plan for at least two to three hours total from start to finish.
