Primary and Extended Partitions

In this section, we start with a clean disk to create the partitions needed to install SUSE. If you want to remove the partitions on an existing installation of an operating system, select the partition and press Delete. You will be asked to confirm this, and the partition will be removed.

If you select Create, you are prompted for the type of partition you want to create (see Figure 1-11). In the PC world, the BIOS can access only four primary partitions. These can be thought of as four physical boundaries on the disk, with separate data and filesystems on each. With Linux, you need at least two partitions, and if you have Windows on another partition and a data or home disk on the other, you may quickly run out of ways to expand the way your disk is laid out. To combat this, logical and extended partitions were designed. An extended partition is a placeholder for further logical partitions. It is a good idea to create one extended partition (which takes up one of your primary partitions) and create logical partitions to accommodate partitioning schemes in the future.
