One of the largest obstacles for a new user during a Linux installation is partitioning. Red Hat Linux makes this process much simpler by providing an option for automatic partitioning.
By selecting automatic partitioning, you will not have to use the Disk Druid or fdisk partitioning tools to assign mount points or allocate space for your installation.
Automatic partitioning will create and assign partitions for you.
If you choose automatic partitioning, you will remove ALL data on ALL partitions of ALL disk drives.
If you have another OS that you want to keep, do not choose this installation class.
If you want to preserve data or another OS, you should choose to partition manually or choose a custom-class installation.
If you would like to partition manually, you can choose either the Disk Druid or fdisk (experts only) partitioning tool.
Use the Back button to choose a custom-class installation, or choose Next if you want to proceed with a server-class installation.
