16.10. Do You Have Enough Disk Space?
Nearly every modern-day operating system (OS) uses disk partitions, and Red Hat Enterprise Linux is no exception. When you install Red Hat Enterprise Linux, you may have to work with disk partitions.
The disk space used by Red Hat Enterprise Linux must be separate from the disk space used by other OSes you may have installed on your system.
For more information about disks and partition configuration, refer to Section 17.14.4, “Recommended Partitioning Scheme”.
