Data loss is a serious problem, especially in the business environment, because it consumes time and sometimes even money to restore or recover information. But let’s take a look at some popular causes of losing data.

What are the most common reasons for data loss?

Data loss can be caused by many different factors, and each poses a unique problem for data recovery:

  • Human errors – We all make mistakes, some of them bigger than others. Without realizing it, you can overwrite important files or delete essential information. 
  • Malware and viruses – These can sometimes corrupt your operating system, stealing important data. Thus, you should keep your antivirus software constantly updated.
  • Hardware damage – Plenty of data loss cases happened because hardware malfunctions. Hard drive failing is the most common explanation to this and there are signs you should consider, such as: frequent hard drive crashes, slow processing speeds, files not opening or being randomly corrupted.
  • Software corruption – It seems like unexpected or improper software shutdowns can cause serious issues for your data. These will lead to data corruption or will simply delete your progress, wasting time and losing valuable information. 
  • Hard drive formatting – Last, but not least, consider that you can accidentally format your hard drive, which instantly causes losing data. Note that reformatting may also occur during system updates and result related troubles. 

Before getting into the steps on how to install the new OS without losing data, you should check if your PC is eligible for Windows 11.

We have an excellent guide on how to download Windows 11 ISO or update from Windows 10 that also will help you find out if your PC is ready for the new OS.

Also, although the solutions we provide here were tested and work, there are a lot of other problems you may encounter so before starting, you should create a backup of all your data just to be on the safe side.

That being said, we’re going to show you some easy ways to install Windows 11 without data loss.

How can I install Windows 11 without data loss?

1. Use Windows Update

  1. Click the Start button and select Settings.
  2. Select Update & Security.
  3. Click on the Check for updates button and you should see Windows 11 as a regular Windows update.

It will start to download and then, the installation will begin. You will also be prompted for a restart.

Watch the process carefully and when asked if you want to keep your files, you should stay on that path.

2. Download the Windows 11 ISO

  1. Navigate to the official Windows 11 Downloads page and click on Select download from Download Windows 11 Disk Image (ISO), then pick Windows 11.
  2. Now click on the Download button.
  3. Select the language, then click the Confirm button. You will receive a download link and you will be able to click on the 64-bit Download button to get the Windows 11 ISO.
  4. Now you can create a bootable USB or DVD, or just right click the ISO and select the Mount option.
  5. You will see a virtual drive in the File Explorer window. Just click on it and then double-click the setup.exe file to start the installation process.

The installation process will start and along the way, you will be asked if you want to keep your files so that’s what you need to choose.

3. Use the Windows 11 Installation Assistant
