We can delete the partition on the disk if we don't need it anymore and an unallocated space will be generated after we delete a partition and we can use this unallocated space to create more partitions or we can simply allocate the unallocated space to extend other partitions on the disk.
Before You Do
After deleting a partition, all the files and data on that partition will also be deleted. So, please back up or transfer those useful data which you don't want to delete from the partition you are going to delete in advance.
If there are other applications running on the partition which you are going to perform, AOMEI Partition Assistant will let you close those applications first.
To Delete Partition
Step1: Select the partition which you want to delete in main window, right-click it and select "Delete Partition" to open the related dialog.
Step2: Select the delete method in the following dialog, and you will see there are two options:
Delete partition quickly: the data which has been deleted is recoverable if you choose this option.
Delete partition and wipe all data to prevent data recovery: If you select this option, then AOMEI Partition Assistant will delete the partition and wipe all data on it. The data which has been deleted usually cannot be recovered by any data recovery software, so please use it with caution.
Choose whichever one according to your needs, after that, click OK.
Step3: Click Apply to execute the operation.
To ensure that your operating system can work properly, AOMEI Partition Assistant won't allow you to delete system partition directly and if you really want to delete this partition, you can create a Bootable Media with AOMEI Partition Assistant so that you can boot your pc from this bootable media to enter in Aomei Partition Assistant's interface to delete the system partition.
