The difficult part is behind you if you are clear about what partitions are and how to use them best for your hard disk.
The easiest way to create the individual partitions is in the order they appear on the hard disk. You then need only indicate the size and type of the respective partition.
The partition type represents a reference to the file system within the partition. However, it is nothing more than a reference. The partition type modification within the partition table does not change the file system.
Many formatting programs use the partition type as the criterion for which file system is to be created.
