1. Reboot the computer

A standard reboot isn't likely to fix this particular issue but it's still worth a try, as it's harmless. Windows will fix this problem in the boot sequence.

2. Rebuild the BCD

If the error persists, rebuilding the Boot Configuration Data file is the great next step to take. Access the Advanced Startup Options menu to get started.

3. Rebuild the BCD with the bootable media

Sometimes Windows startup problems are difficult to fix because you can't access the repair tools you need to use. While you can use another Windows installation drive, a simpler method is to create and use a Windows 10 bootable USB. To create an ISO, download the Windows ISO (free) from one of Microsoft sources, then create bootable USB.

When it's done, rebuild the BCD in Windows like you probably did in the previous troubleshooting step, but this time, boot into the USB key, not the primary drive.

4. Perform a system restore

If repairing the BCD doesn't fix the problem, a more drastic approach is to restore the system to an earlier point in time. Using System Restore can delete apps and data, so if possible, back up anything important to a secondary drive before proceeding. However, you will need to run the recovery option from the Advanced Startup Options menu , as you cannot boot into Windows properly.

5. Format the partition and reinstall Windows

If you're still having trouble starting your PC after completing the steps above, format the drive and reinstall Windows. Back up any important information on the drive, as this will wipe the drive.
