How to make a backup of your entire computer for Windows 10/11?

Using Windows PE (Preinstallation Environment) to make a backup of your entire computer is possible and can be a very effective method, especially if your system is unbootable or you want a clean, standalone environment for backup purposes.

What is Windows PE?
Windows PE is a lightweight version of Windows designed for deployment and recovery.
It can be booted from a USB drive or DVD.
It allows you to run tools without relying on your installed Windows OS.

How to make a backup of your entire computer?

1. Create a Windows PE Bootable Media
Download the Windows ADK (Assessment and Deployment Kit) from Microsoft, which includes Windows PE.
Use the Deployment and Imaging Tools Environment (a command prompt with specific tools) to create a bootable USB or ISO.

Steps:
Download and install the Windows ADK from Microsoft.
During installation, select the Windows Preinstallation Environment (Windows PE) component.
Use the MakeWinPEMedia command to create bootable media:

MakeWinPEMedia /ISO C:\WinPE_amd64 C:\WinPE.iso

Alternatively, create a bootable USB:

MakeWinPEMedia /UFD C:\WinPE_amd64 F:

(Replace C:\WinPE_amd64 and F: with your actual paths)

2. Boot into Windows PE
Insert the bootable USB or DVD.
Boot from it (change boot order in BIOS if needed).
Windows PE loads into a minimal environment with command-line tools.

3. Use Backup Tools in Windows PE
You can use DISM, ImageX, or third-party tools compatible with Windows PE.
Robocopy or xcopy can also be used for file-level backups.
For full disk image backups, consider using ImageW or Clonezilla (if integrated).

4. Store the Backup Safely
Save the image to an external drive or network location.
Ensure the backup is complete and verify integrity if possible.

5. Restore the Image (if needed)
Boot into Windows PE again.
Use DISM or other imaging tools to restore your system from the backup.
