Choose where you would like CentOS to be installed.
If you do not know how to partition your system, please read the section on partitioning in the CentOS Installation Guide.
If you used automatic partitioning, you can either accept the current partition settings (click Next), or modify the setup using Disk Druid, the manual partitioning tool.
If you just finished partitioning with fdisk, you must define mount points for your partitions. Use the Edit button, once you have chosen a partition, to define its mount point.
If you are manually partitioning your system (using Disk Druid), you will see your current hard drive(s) and partitions displayed below. Use the partitioning tool to add, edit, or delete partitions for your system.
Note, you must create a root (/) partition before you can proceed with this installation. If you do not create a root partition, the installation program will not know where to install CentOS. You must also create a /boot/efi partition of type vfat. The /boot/efi partition contains all the installed kernels, the initrd images, and ELILO configuration files.
The graphical representation of your hard drive(s) allows you to see how much space has been dedicated to the various partitions created.
Below the graphical representation, you will see a filesystem hierarchy showing your existing partitions. Using your mouse, click once to highlight a partition or double-click the partition to edit it.
The center row of buttons controls the partitioning tool's actions. You can add, edit, and delete partitions here. In addition, there are buttons you can use to accept the changes you have made, or to reset and exit the partitioning tool.
New: Use this button to create a new partition. A dialog box will appear containing fields that must be filled in (such as mount point, filesystem type, drive that the partition should exist on, size, and so on).
Edit: Use this button to change the mount point of a currently selected partition. You can also manually create a partition by editing free space (if available). Editing free space in this sense is similar to using fdisk in that you can choose where the partition begins and ends within that free space.
Delete: Use this button to delete a partition.
Reset: Use this button to cancel your changes.
Make RAID: Use the Make RAID button ONLY if you have experience using RAID. To learn more about RAID, refer to the CentOS Customization Guide. To make a RAID device, you must first create software RAID partitions. Once you have created two or more software RAID partitions, select Make RAID to join the software RAID partitions into a RAID device.
