5.3 Installation Error Recovery

If the screen shown in Figure 5-19 appears, use the following steps to install an unsigned driver one time.

  1. Click Start and select Settings
  2. Click Update and Security
  3. Click Recovery
  4. Click Restart Now under Advanced Startup
  5. Click Troubleshoot
  6. Select Advanced Options
  7. Select Startup Settings
  8. Click Restart
  9. On the Startup Settings screen, press F7 during reboot to disable driver signature enforcement. The host computer restarts.
  10. Repeat the entire re-installation process
  11. A message appears informing that installing .NET failed. Close that window and continue.
  12. Double-click Install unsigned drivers

After restarting a second time, the host computer resets. The reset requires all drivers to be digitally signed the next time a default installation executes, unless these steps are repeated.
