It’s a situation most computer users dread — your computer is acting up, and you’ve tried everything you can think of to fix it. The last resort is often to reinstall Windows 10. While this may sound daunting, it’s actually a relatively straightforward process that can solve many issues with your computer.

If you’re new to the world of computers, don’t worry — this beginner’s guide will walk you through the steps of reinstalling Windows 10 from start to finish.

What Is Reinstalling Windows 10?

Reinstalling Windows 10 is the process of removing the current operating system from your computer’s hard drive and starting over with a fresh installation. This is akin to hitting a reset button on your machine, allowing it to start anew with a clean slate.

The Basics of Reinstalling

When you reinstall Windows 10, you’re effectively clearing your hard drive and installing a new, untouched version of the operating system. This can resolve problems that are too complex or deep-rooted to fix with standard troubleshooting.

Preparing for a Fresh Start

Before you begin, it’s important to understand that reinstalling will erase your data. Therefore, preparing for reinstallation involves backing up your files, gathering necessary software licenses, and ensuring you have the resources to restore your programs and settings.

When Reinstallation Is the Best Option

Reinstalling Windows 10 is a last-resort measure. It’s best considered when other troubleshooting efforts, such as running system checks, updating drivers, or scanning for malware, have failed to resolve persistent issues.

Why Would I Need to Reinstall Windows 10?

There are several situations when reinstalling Windows 10 could be beneficial. Here are some of the most common reasons:

Dealing with Persistent Viruses and Malware

In cases where your computer is infected with malicious software that refuses to be purged, a clean installation of Windows 10 might be the only surefire way to eradicate the threat completely.

Resolving System File Corruption

When vital operating system files become damaged or corrupted, they can cause your system to become unstable. Reinstalling Windows 10 can replace these files with fresh, undamaged versions.

Frequent Crashes and Errors

Experiencing frequent system crashes and errors can be frustrating. If these issues persist and defy all attempts at repair, starting fresh with a new Windows 10 installation might be your best option.

Desire for a Clean Slate

Some users prefer to periodically start fresh with a clean installation of Windows to keep their system running optimally. It’s a way to declutter your digital space and often leads to improved performance.

Before You Begin: Back Up Your Data

Before embarking on the journey of reinstalling Windows 10, it’s absolutely critical to back up your data. This section will guide you through the necessary steps.

Understanding What to Back Up

Identify which documents, photos, videos, and other personal files are important to you. Additionally, remember to back up application data, such as game saves or custom settings, which are often overlooked.

Selecting a Backup Method

There are multiple ways to back up your data. You could use an external hard drive, a cloud-based service, or even a series of USB flash drives. The key is to choose a method that’s reliable and accessible to you.

Executing the Backup

Once you’ve chosen your backup method, execute the backup. Ensure that your files are copied in an organized manner so that you can easily restore them after the reinstallation process.

How to Reinstall Windows 10 from BIOS

Reinstalling Windows 10 from the BIOS is a solid approach, especially when dealing with a severely compromised system. This section will walk you through each step in detail.

Step 1: Create a Windows 10 Installation Media

To start, you need to create a bootable USB drive with the Windows 10 installation files. Tools like Rufus or the official Windows 10 Media Creation Tool are excellent choices for creating this media.

Step 2: Access the BIOS

Reboot your computer and press the appropriate key to enter the BIOS. This is typically one of the function keys (like F2 or F10), but it can vary based on your motherboard manufacturer.

Step 3: Change the Boot Order

Inside the BIOS, navigate to the boot section and adjust the sequence so your computer starts from the USB. This will allow your machine to boot into the Windows 10 installer instead of your existing operating system.

Step 4: Reinstall Windows 10

Once you’ve booted from the USB drive, follow the on-screen instructions to reinstall Windows 10. Choose to perform a clean install, wiping all data from your drive and installing a fresh version of the OS.

How to Reinstall Windows 10 to a New Hard Drive

Replacing your hard drive may necessitate reinstalling Windows 10. This could be due to an upgrade or a drive failure.

Step 1: Back Up Your Data

Again, back up all your important data. This step is crucial as you’ll be removing the old drive, which contains all your files.

Step 2: Create a Windows 10 Installation Media

Create the bootable USB drive with the Windows 10 installation files if you haven’t already done so in the previous steps.

Step 3: Replace Your Hard Drive

Carefully replace the old drive with your new one. This might require some technical knowledge, so refer to your computer’s manual or get professional help if needed.

Step 4: Reinstall Windows 10

With the new drive installed, boot from the USB and install Windows 10 onto the new hard drive, following the same process described earlier.

How Do I Reinstall Windows 10 Without Losing Data?

It’s possible to reinstall Windows 10 without losing your personal files by choosing an option that upgrades your current installation rather than performing a clean install.

Understanding Non-Destructive Reinstallation

This type of reinstallation preserves your files, settings, and programs. It’s a way to refresh the operating system without the loss of important data.

Performing an In-Place Upgrade

An in-place upgrade can be initiated directly within Windows or by using the installation media you’ve created. This process will reinstall Windows 10 while keeping your files intact.

Considerations and Risks

Although an in-place upgrade is designed to preserve data, it’s still wise to back up important files. The process is complex, and there’s always a slight risk of data loss.

How Do I Reinstall Drivers on Windows 10?

Drivers are essential for your hardware to communicate effectively with Windows 10. After a reinstallation, you may need to update or reinstall drivers.

Step 1: Access Device Manager

The Device Manager is your starting point for managing hardware and drivers. Right-click the Start button and select it from the power user menu.

Step 2: Locate the Device You Want to Update

In Device Manager, look for the piece of hardware you need to update. Expand the relevant category and find the device in question.

Step 3: Update the Driver

Right-click the device and opt to update the driver. You can search automatically for updated driver software or browse your computer for driver software if you have it on hand.


Reinstalling Windows 10 may seem like a daunting task, but it’s a straightforward process that can breathe new life into your computer. By carefully following the steps in this beginner’s guide, you can tackle the reinstallation with confidence.

Remember to back up your data before starting, and if you ever feel unsure about the process, consult your computer’s manual or seek the assistance of a professional. With a fresh installation of Windows 10, your computer will be set for stable and efficient performance.
