Using the Cross OS Undo feature to undo a previous repair session of Norton Power Eraser

In some cases, the files that are infected on your computer can be the Windows files required to boot your computer. Norton Power Eraser can still detect and repair an infected Windows file. However, modifying or repairing a Windows file may make your computer unbootable.

If you cannot boot your computer after removing a threat from your computer using Norton Power Eraser, you may need to undo the repair session. Norton Power Eraser comes with a Cross OS Undo feature with which you can undo a repair session by booting into the computer using a different operating system.

If your computer is installed with multiple operating systems, which are configured for a multi-boot, you can log on to your computer using the other working operating system. After that, start Norton Power Eraser from there to use the Cross OS Undo feature.

Undo a previous repair session using the Cross OS Undo feature

  1. Start your computer using a different operating system.

  2. Browse to the location where the Norton Power Eraser tool is saved, and double-click the NPE.exe file to start it.

  3. Read the license agreement, and click Accept.

  4. In the top-right corner, click Settings.

  5. Select Enable Multi-Boot check, and then click OK.

  6. Click Undo Previous Fix.

    Norton Power Eraser checks and displays all the repair sessions for the current operating system and other non-host operating systems on the computer.

  7. Select the operating system and user combination from the list.

  8. Select the repair session that you want to undo, and click Next.

    The repair session entry for a non-host operating system that fails to boot, displays the operating system as Target OS next to it.

  9. Review the fixes that are performed in the selected repair session. Select the files that you want to restore, and then click Undo.

  10. If Norton Power Eraser prompts you to restart the computer, then click Restart Now.

  11. Norton Power Eraser displays the files that were restored. Click Done.

Thank you!
