Overview

This guide is designed to help you recover data from a previous Windows installation while installing Windows 11 on a laptop. The process involves several steps, including preparation, data recovery, installation, and post-installation. We'll use built-in Windows tools and third-party software to ensure a successful data recovery and installation.

Preparation

Before you begin, make sure you have the following:

A laptop with a lost partition or data after a Windows reinstall
An installation media for Windows 11 (USB drive or DVD)
A backup of important data (if available)
Third-party data recovery software (optional)

Data Recovery

To recover data from the previous Windows installation, follow these steps:

In the Windows Setup window, click Next, then click on Repair your computer in the lower-left corner.
In the Choose an option screen, click on Troubleshoot.
Click on Advanced options.
Click on Command Prompt to open a command-line interface.
Enter the following commands to check the disk for errors and recover any recoverable data:


diskpart
list volume
select volume 
assign letter=X
exit
chkdsk X: /f /r

Replace volume_number with the number of the partition containing the lost data. This process may take some time, depending on the size of the partition and the amount of recoverable data.
