After Deeper Search partitions are often displayed as D (deleted). You can change the status of the selected partition using the left/right arrow key. The available statuses are Primary, * bootable, Logical, and Deleted.
Primary Partitions
The first primary partition usually starts at cylinder 0, head 1, sector 1.
Additional primary partitions are starting at a non-nul cylinder, head 0, sector 1.
Example:
