Unallocated partitions are essentially blank spaces on your hard drive with no assigned purpose. They can occur due to a variety of reasons, such as incomplete installations, accidental deletions, or a factory-reset state. These empty spaces may seem harmless, but they can affect your system’s performance and hinder efficient disk management. Recognizing the characteristics and impact of unallocated partitions is the first step to managing your system effectively.

Preparing for Deletion

Before diving into the deletion process, it’s crucial to take some preliminary steps. First and foremost, **back up any important data** that might reside on the unallocated partition.

Merging Unallocated Space

Once the unallocated partition is deleted, you have two primary options for utilizing the now available space. One option is to **expand an existing partition** that requires more space.
