As some users have pointed out, the issue can also be caused by an external device connected through USB. To pinpoint the culprit, every external drive and non-necessary peripheral (mouse, keyboard) and reboot to see if the error returns.

If your computer starts up just fine, systematically connect the rest of peripherals until you pinpoint the cause of the error. Once the culprit is identified, uninstall the driver belonging to that peripheral via Device Manager in order to force Windows to reinstall it. Here’s a quick guide on doing this:

1. Press Windows key + R to open up a Run box. Then, type “devmgmt.msc” and press Enter to open up Device Manager.

You can always go of a clean install, but a more elegant solution would be to perform a repair install. This procedure will reinitiate all Windows files while allowing you to keep all your personal files and applications.
