FIX: Cannot Delete Partition on Windows 10/8/7/Vista (Solved)

If you cannot delete a partition on Windows using the Disk Management utility because the "Delete Partition" option is greyed out, then probably the partition is an "EFI System" partition or a "Recovery Partition". These type of partitions (EFI & Recovery) are system protected partitions and for that reason they cannot be deleted by using the Windows Disk Management utility.

In this tutorial you will find detailed steps on how to remove partitions (including the system protected Partitions, EFI or Recovery) using the DISKPART utility. *

Caution: The System Protected Partitions on the main (OS) disk, should not be erased because your system will not be able to boot. The instructions below, shows how to delete partitions on a secondary disk, that cannot be deleted using the Disk Management tool.
