If you have blank Hard disk, Only Linux partitions required.
You have two choices, a single Operating System (OS) or a multi-boot system.
Many desktop users like to run Linux in addition to Windows on an existing PC. An additional hard drive may be used for Linux or an existing drive may be sectioned into two or more partitions. Linux may also reside as the only operating system on the computer as is preferred by those creating a server. Using a separate drive for Linux is the easiest and the preferred multi-boot configuration because it allows the original Windows drive to remain intact.
Note: Re-partitioning a drive will destroy all data on the drive unless a tool such as partition magic or fips is used. The Red Hat CD-ROM includes the repartitioning tool "fips" in the dosutils directory. See /dosutils/fipsdocs. This tool is unsupported. Partition Magic would be a wiser choice for those pursuing this approach. For dual boot installations, MS/Windows can be re-installed allowing the Microsoft installer to repartition the drive.
