Rebuild Windows EFI boot

#windows #tutorial

If your Windows computer is showing the Blue Screen of Death with the error code 0x0000001 or 0x00000098, you're required to rebuild the Windows EFI boot to continue booting Windows as before.

To do the following steps, you require an USB drive with a bootable Windows installer. Boot your computer with the USB drive and enter the recovery mode so you get a command prompt.

Once you have the command prompt, run the following commands one by one carefully as some might be different on your computer.

We enter the DiskPart utility.

diskpart
Enter fullscreen mode Exit fullscreen mode

Now, we should find the disk where Windows is installed.

list disk

  Núm Disco  Estado      Tamaño   Disp     Din  Gpt
  ---------- ----------  -------  -------  ---  ---
  Disco 0    En línea        953 GB      0 B        *
Enter fullscreen mode Exit fullscreen mode

And we select it.

select disk 0

  El disco 0 es ahora el disco seleccionado.
Enter fullscreen mode Exit fullscreen mode

Next, we should find the volume that contains the boot. Usually it uses FAT32 and has a size of 100 MB.

list volume

  Núm Volumen Ltr  Etiqueta     Fs     Tipo        Tamaño   Estado     Info
  ----------- ---  -----------  -----  ----------  -------  ---------  --------
  Volume 0     C                NTFS   Partición    952 GB  Correcto   Arranque
  Volume 1                      FAT32  Partición    100 MB  Correcto   Sistema
  Volume 2                      NTFS   Partición    786 MB  Correcto   Oculto
Enter fullscreen mode Exit fullscreen mode

And we select it.

select volume 1

  El volumen 1 es el volumen seleccionado.
Enter fullscreen mode Exit fullscreen mode

Next, we format it to delete all it's content.

format fs=fat32 quick
Enter fullscreen mode Exit fullscreen mode

Once formated, we assign an availabe letter to our volume.

assign letter T:

  DiskPart asignó correctamente una letra de unidad o punto de montaje.
Enter fullscreen mode Exit fullscreen mode

And we exit DiskPart utility.

exit
Enter fullscreen mode Exit fullscreen mode

Now we rebuild the Windows EFI boot by pointing it to our Windows installation.

bcdboot C:\Windows /s T:
Enter fullscreen mode Exit fullscreen mode

Ensure you're Windows installation is located at C:\Windows before running this command.
