Restaurar el arranque de Windows con el entorno de recuperación Iperius
El Entorno de Recuperación de Iperius es el sistema de recuperación diseñado específicamente para Iperius Backup. Se puede descargar directamente desde el software y se puede iniciar desde un dispositivo USB o un CD-ROM.
Además de la posibilidad de restaurar copias de seguridad de imágenes de unidad de Iperius, como se explica en nuestro tutorial detallado , este entorno también permite realizar operaciones avanzadas del sistema, solucionando diversos problemas que pueden surgir tras restaurar una copia de seguridad.
En esta guía, veremos cómo restaurar el arranque de Windows en caso de errores de inicio mediante comandos de terminal sencillos.
Antes de continuar, asegúrese de haber creado correctamente el entorno de recuperación de Iperius en su dispositivo (USB o CD-ROM) siguiendo las instrucciones del tutorial .
Una vez que la PC se haya iniciado desde el medio USB (o CD-ROM), inicie el símbolo del sistema haciendo clic en el ícono correspondiente (ver la imagen a continuación).
Se abrirá el símbolo del sistema clásico, donde podrá usar los mismos comandos que en la versión estándar de Windows.
Escriba el comando diskpart y presione “Intro”. El lado izquierdo de la consola cambiará del directorio inicial (p. ej., X:\windows\system32 ) a la palabra ” DISKPART “, lo que indica que la utilidad se ha iniciado correctamente (ver imagen a continuación).
Ahora, escriba el comando ” list disk” para mostrar la lista de discos conectados al sistema, con información como número, tamaño y tipo de formato (GPT o MBR).
Localice el disco donde restauró la imagen, utilizando la información de tamaño o índice del disco.
Anote el número de disco y verifique el tipo de formato: si hay un asterisco debajo de la columna GPT, el disco está formateado en GPT; de lo contrario, está en MBR.
En este punto, el tutorial se dividirá en dos partes: seguir el punto A) si el disco es GPT, o el punto B) si es MBR.
A) GPT Disk
If the disk is GPT, the command list disk will return a result similar to the one in the image below (concerning the disks connected to the system).
In the red box, you can see the general output, while in the yellow box, the disk where the Iperius Drive Image backup was restored is visible. Write down the disk number, which will be needed for the next step.
In our example, the disk is number 0 (“zero”).
Next, execute the command select disk X (where X is the number we noted), followed by the command list partition.
The output will be similar to the one shown in the following image:
In the red box, you see all the partitions on the disk, with information like index, type, and size. In yellow, the system partition (System), also called EFI, where the BCD (Boot Configuration Data) file is located, is highlighted. This is the file you will repair to restore the boot.
Select the partition by typing select partition Y (where Y is the partition index) and press Enter.
In our case, the system partition is number 2, as shown in the image above.
Now you need to assign a drive letter to the partition to identify it. To do this, type the command assign letter=S and press Enter, as shown in the following image:
At this point, you can access the system partition volume through the letter S: .
Now you need to locate the volume where Windows is installed. Run the command detail disk to view all volumes on the disk with their related information.
In the result, identify the volume where Windows is installed, using size and/or filesystem as a reference. If it doesn’t have a drive letter, you can assign one with the assign letter command.
In our case, the drive letter is C:, as shown above.
Exit Diskpart with the command exit.
Now the command prompt will return to the initial screen with the path X:\windows\system32.
Proceed to the “Boot Restore” section to complete the tutorial.
B) MBR Disk
If the disk is MBR, the command list disk will return a result similar to the one shown in the image below.
In the red box, you see the general output, while in the yellow box, the disk where the backup was restored is visible. Write down the disk number, which will be needed for the next command.
In this example, the disk is number 0 (“zero”).
Proceed with the command select disk X (where X is the noted number) and then detail disk.
The output will display information about the volumes present on the disk.
In the result, you can see the volume of the system partition (System Reserved) (in yellow), where the BCD file is located.
Select this volume with the command select volume Y (where Y is the volume index) and press Enter.
Note: if the system partition is not present, refer to the additional note 2 at the end of the tutorial for more details.
If the “Ltr” column is empty, assign a drive letter with the command assign letter=S.
Then proceed to identify the volume where Windows is installed, as described above.
Once the volume is found, check if it has a drive letter. If needed, assign one manually.
Exit Diskpart with exit, then continue with the “Final Step: Boot Restore” section to complete the guide.
Final Step: Boot Restore
Once you have completed the previous steps, you are ready for boot restore. Run the command:
bcdboot C:\Windows /s S: /f ALL
This command will copy the boot data from C:\Windows to the system volume, updating the BCD file.
If everything went well, you will see output similar to this:
Exit the command prompt by typing exit and pressing Enter.
Now you are back at the main screen of Iperius Recovery Environment.
To finish, click Shutdown/Reboot, remove the USB (or CD-ROM) media, and choose whether to reboot or shut down the PC. Confirm with OK.
Upon restart, the operating system will boot correctly.
A hardware change, a partition error, or the deletion of system files are just some of the causes of Windows not booting.
Thanks to this tutorial, you have learned how to quickly and safely restore the boot without compromising data.
Additional Notes
¹ If the letter S is already assigned to another volume, the utility will return this error:
In this case, repeat the command choosing a free letter.
² In a system with an MBR disk, it may happen that the system partition is not present. However, it is still possible to restore the boot by simply marking the Windows partition as the active system partition.
To do this, follow the steps above to assign a drive letter to the Windows partition if there isn’t one already, and of course skip the entire section regarding the system partition
Before exiting diskpart, with the Windows partition selected from the previous operation, type the command active and press Enter. This will make the partition recognized as the one to boot the system from.
En este punto, salga de diskpart y utilice el siguiente comando para restaurar el arranque (en nuestro ejemplo, a la partición de Windows se le ha asignado la letra C 🙂
bcdboot C:\Windows /s C: /f TODOS
En comparación con el comando genérico, podemos ver cómo la partición de Windows se utiliza como partición del sistema (sigue al atributo /s ).
