5. Select Fixed size to make the partition the specified size, select Fill all space up to (MB) and
enter a size in MBs to give range for the partition size, or select Fill to maximum allowable size

growable, they share the available free space on the disk.
6. Select Force to be a primary partition if you want the partition to be a primary partition. A
primary partition is one of the first four partitions on the hard drive. If unselected, the partition is

this option should be considered. For more information on primary versus logical/extended
partitions, refer to the appendix section of the Installation Guide.
7. Click OK to return to the main screen.
Repeat these steps to create as many partitions as needed for your RAID setup. Notice that all the
partitions do not have to be RAID partitions. For example, you can configure only the /boot/ partition
