Disk partitions are a standard part of the personal computer landscape and have been for quite some time. However, with many people purchasing computers featuring pre-installed operating systems, relatively few people understand how partitions work. This chapter attempts to explain the reasons for and use of disk partitions so your Red Hat Enterprise Linux installation is as simple and painless as possible.

If you are reasonably comfortable with disk partitions, you could skip ahead to Section C.1.4, “Making Room For Red Hat Enterprise Linux”, for more information on the process of freeing up disk space to prepare for a Red Hat Enterprise Linux installation. This section also discusses the partition naming scheme used by Linux systems, sharing disk space with other operating systems, and related topics.
