How to Delete All Partitions on a Hard Drive?

Overview of Delete Partitions

Once, one of my neighbors asked me to help with his computer and I was always invited to solve PC problems by my neighbors and friends since I was engaged in this software company and I was happy that I could help him make full use of our partition manager.

Actually, he wanted to extend his c partition but he did not have an unallocated space on his computer and he did not want to merge any other partition to c except f, but partition f was not adjacent to c. Still, if he could merge f with c, he did not need the data on it any more. In such case, just as I told him, he should delete f partition first to get an unallocated space. Then, he could enlarge c partition with the unallocated space. Like this, he got all he intended. It was easy and not difficult as what he expected.
