bootrec /rebuildbcd errors

But why did the error occur? I really don't want to use an usb...

Hi,

Does the Windows installation actually still exist?

C:

bootrec /fixmbr

bootrec /fixboot

bootrec /scanos

bootrec /rebuildbcd

After the above you may need to run StartUp Repair (even 2 or 3 times)

Using EasyBCD often works when other methods do not. <-- if Bootrec did not help use this.Translate the Windows 8/8.1 methods to Windows 10.

Try to enter Safe Mode to repair Windows.

Interrupt the normal boot process of your Windows 10 PC

If Windows 10 fails to boot normally three times over, the fourth time it enters by default in an Automatic Repair mode. Using this mode, you can boot into Safe Mode. To trigger the Automatic Repair mode, you must interrupt the normal boot process three consecutive times: use the reset or the power button on your Windows 10 PC to stop it during boot, before it finishes loading Windows 10. If you use the power button, you might have to keep it pressed for at least 4 seconds to force the power off

Then you proceed to repair the computer:

With a reset, all of your Installed applications are lost, but you get an option to save your files if you want. If a system image from the OEM exists-called a recovery partition, then it also gives you an option to restore it. It would make your PC load to default factory settings.

Navigate to Troubleshooting section, again.

Select Reset.

If you select keep my files, your files would be kept. You might also get the third option-restore to factory settings-which isn’t applicable on the PC.

After selecting the desired options, you are presented with a confirmation, something like this- This indicates what you have chosen.

Click on Reset and the resetting should begin.
