How to delete a partition using fdisk

Before deleting a partition, you must be aware that deleting a partition deletes all information on the hard disk.

First, before deleting the partition, determine which partition is currently configured on the hard disk by displaying the partition information. To do this from the fdisk menu, select:

4 - Display partition

Once the partition information is displayed, check the defined “Type” of the partition. The type can be PRI DOS or NON-DOS:

PRI DOS = primary DOS partition
NON DOS = Non DOS partition

If an extended or logical DOS partition is defined, you can view this information to determine if a logical partition is defined in the extended partition.

EXT DOS = extended DOS partition

How to Delete a Primary Partition

If you have an extended or logical partition, you cannot remove the primary partition until the extended partition is wholly removed. See the next section for information on how to do this.

From the fdisk menu, select:

3 - Delete primary partition
1 - Delete primary DOS partition, select 1 to delete primary partition and enter volume label as shown above on your screen, if no volume label is specified just press enter.
