Here are some instructions to fix the issue by running NPE from an NBRT boot disk, rather than by running it on the infected partition itself. This may be able to get around the problem.
Create NBRT boot disk or USB key using a clean, working computer:
1. Visit http://security.symantec.com/nbrt/nbrt.aspx?
2. Select the "Download Now" option which applies to your Norton license type.
3. After it’s done downloading, launch NBRT-Retail-Downloader.exe, this will launch Norton Download Manager.
4. Go through the on screen directions to complete the install.
4. After the install completes, use the Norton Bootable Recovery Tool Wizard.
5. Select "Create on CD/DVD media" or "Create on USB key" depending on which is most convenient.
6. Complete the wizard to create a boot disk / boot USB key.
On the infected/unbootable computer:
1. Boot from the USB key or CD/DVD you created.
1. You may need to adjust the boot order settings in BIOS to avoid booting from the hard drive. Instructions for doing this can be found in the documentation for your motherboard.
2. If using a CD/DVD, when you start the computer hit any key when it says "Press any key to boot from CD..."
After you boot into NBRT:
1. Enter your product key or pin
2. Select "Norton Power Eraser Recovery Scan"
3. Click the History button
You should see multiple choices for Operating system.
4. Choose the operating system installed on the computer (not WinPE).
5. Select the session for which risks were removed and the boot issue arose.
6. Click Next
7. Click Undo
8. Review results (make note of any failures) and click Done
9. Click Exit, click Exit
The computer should reboot
