SCREENSHOT 12) Select the disk for the installation and choose between the default or custom disk configuration.

The two options are “Use an entire disk”, which will use and DELETE all the data in the selected disk (the selected disk is with a check before the line with the disk name), and “custom storage layout”, which will start a partition layout wizard and it will expect the user to manually modify (remove, create, modify?) the disk layout. For simplicity, we “use the entire disk” option, which is the most commont when installing in a server where dual boot is not so common.
