Windows Boot Manager (WBM) is a program that helps you to manage your computer’s startup sequence. It can be used to start your computer automatically when you insert a disk or USB drive, or when you connect it to the network. If WBM isn’t working properly, it can cause your computer to not start up at all. To fix this, you need to first check if WBM is working correctly. If it is, then you can fix the problem by following these steps:

  1. Open WBM and click on the “Settings” button.
  2. Under “Boot Manager,” select “Check for updates.”
  3. If WBM isn’t working properly, then you will need to update it. To do this, open WBM and click on the “Update” button. Once updated, restart your computer and try again to start up WBM.
