Extend boot partition in Windows Server 2012 R2

Boot partition is the drive where Operating System located. Most of the Windows users encountered the issue that little free space is left in boot partition, because tons of files are saving to the drive continuously. The same with other Windows versions, in Server 2012 you’ll encounter this problem sooner or later, even if you created a large C drive. To solve this problem, the best idea is extending boot drive with free space in other partitions. In this article I’ll show you how to resize/extend boot partition in Windows Server 2012 (R2) without data loss.

Partición de arranque VS Partición del sistema

Some people do not know the difference between boot partition and system partition, and most of these people thought that system partition is definitely the drive of Operating System. To identify, simply open Disk Management console.

Partición de arranque del sistema

Como puede ver, la partición de arranque también es la unidad C y la partición reservada del sistema está marcada como Sistema.

En resumen, la partición del sistema es la partición primaria para iniciar Windows. La partición de arranque es donde se encuentran los archivos del sistema operativo Windows. En versiones anteriores de Windows, tanto el sistema como la partición de arranque son unidades C.

Poco espacio en disco en la partición de arranque

Como dije al principio, el poco espacio libre en disco es el problema más común en todas las versiones de Windows. Pero a diferencia de la versión anterior como Server 2003, 2008, en Server 2012 no hay Advertencia de "poco espacio en disco" por defecto. En cambio, la partición de arranque (C: unidad) cambió a rojo al abrir Mi PC o Windows Explorer. En esta situación, puede intentar liberar espacio en disco. In general, if you cannot reclaim over 20GB free space, you’d better expand the boot partition, otherwise, it will become full again in a short time.

To extend boot volume in Windows 2012 server, you may try native Disk Management tool or third party software. Because of many limitations, Disk Management is not the best choice. Before extending the boot drive, you must delete the contiguous partition. In some cases, you still cannot extend Server 2012 boot partition after deleting the contiguous volume.

Third party software is much more powerful and you don’t have to delete any partition. However, you’d better run the safest tool, otherwise there’s potential system/data damage risk. Make a backup before any operation to a server. Better than other disk partition software, NIUBI Partition Editor has powerful Virtual Mode, 1-Second Rollback and Cancel-at-well technologies to protect your system and data.
