AOMEI Backupper cannot find the system partition (solution)

Updated: October 3, 2026

This step-by-step guide shows how to fix the "The program did not find the system partition. Please reboot the system and try again." error in AOMEI Backupper on Windows 10 and 11.

This issue is typically caused by the Memory integrity (Core Isolation) feature in Windows Security, which prevents AOMEI Backupper from loading its required drivers. Disabling Memory integrity allows the software to properly detect your system partition and complete the backup.

Solution

1. Open Windows Security by clicking the small shield icon in the system tray.
   
2. Click Device security.
3. Click Core isolation details.
4. Turn off Memory integrity.
5. Restart your PC.

You can re-enable Memory integrity after completing the backup.
