Here are details on fdisk command

Don’t edit partitions while they’re in use. If you want to edit system partitions, boot from a live CD first.

Start with sudo fdisk -l and determine the name of the partition you want to delete (sda1, sda2, etc).

Then, sudo fdisk /dev/sdax with 'sdax' being the drive you would like to delete. This will enter command mode.

After in command mode, (type 'm' if you want the help menu) you will use 'p' to delete the partition. After this, it prompts for partition number, which is just the 'x' from 'sdax'. Then use 'w' to actually write the change.
