Introduction

If you are wondering “how do I remove Windows 10 from my computer without losing data,” you’re not alone. Many users want to uninstall Windows 10 safely—maybe because the system feels slow, updates have become annoying, or you want to switch to another OS like Windows 8.1 or Linux. Removing an operating system sounds complicated, but if you follow the right method and take care of your files, it becomes surprisingly easy.

The real challenge is doing everything without losing a single photo, document, or project. Windows 10 stores your data across multiple locations, and a careless reinstall can wipe everything. That’s why this guide focuses on data-safe methods and step-by-step clarity.

By the end, you will understand every practical approach, including how to back up your data, how to delete Windows 10 from a hard drive, how to completely remove Windows 10 from a PC, and how to reinstall another OS over it.

Why People Remove Windows 10 (And It’s More Common Than You Think)

People uninstall or replace Windows 10 for many reasons, such as:

Slow performance due to heavy updates

Forced reboots after updates

Wanting to switch to Linux for speed and security

Returning to Windows 8.1 due to better stability on older PCs

Removing corrupted system files

Escaping never-ending update notifications

For some users, Windows 10 simply does not fit their workflow anymore—especially when lightweight systems like Linux Mint or Windows 8.1 run smoother on older hardware.

Benefits of Removing Windows 10 Without Losing Data

Uninstalling Windows 10 properly comes with some major benefits:

✔ Save All Important Files

You keep your photos, downloads, documents, and videos safe.

✔ Fix Update Problems

If you want to uninstall Windows 10 updates permanently, reinstalling or switching OS removes update-related bugs completely.

✔ Boost Your System Speed

A clean OS always runs faster than an over-updated Windows 10 installation.

Preparations Before You Remove Windows 10

Before learning how do I remove Windows 10 from my computer, these steps are essential for protecting your data.

1. Backup Your Files

You can use:

External hard drive

USB pen drive

Cloud services (Google Drive, OneDrive, Dropbox)

Another internal partition

Tip: Always backup Desktop, Documents, Pictures, and Downloads—these folders hold most user data.

2. Check Your System Partition

Open Disk Management and verify:

Which partition contains Windows 10

Whether you have another partition for data

Whether you want to delete the Windows 10 partition from the computer

3. Prepare Your Replacement OS

You must have one ready:

Windows 8.1 ISO

Linux ISO

Windows 11 ISO

Bootable USB drive

Your next step depends on whether you want to erase Windows 10 and reinstall Windows or install another OS.

Method 1: Remove Windows 10 and Install Another OS (Safest Method)

This is the safest method if you want to keep your data untouched. Here’s how it works:

Step 2: Restart and Enter Boot Menu

Common keys: F2, F12, Esc, Delete.

Step 3: Select the USB Drive

Your PC will now boot into the installer.

Step 4: Delete the Windows 10 Partition Only

Confirm deletion

This process helps you completely remove Windows 10 from the PC while keeping your files safe in other partitions.
