we are going to use the cfdisk utility for this since it is a bit easier and user-friendly.cfdisk /dev/sdbTo create a new Partition highlight the "Free space" and select "New" at the bottom
you can now enter the desired space for the partition.In this View, you can delete a partition by highlighting it and selecting the "Delete" button.
If you made any changes select "Write" to save them to the disk.
