A Disk Partition is a logical section of a hard disk on which the computer can write data. Partitions offer a way to divide the space on a single physical hard disk into multiple areas, each of which is treated as a different disk within OS.
Some people create separate partitions to help organize their files. For example, you might store the Windows system files and application files on one partition, user-created documents on another partition, and backup files on another partition. Another reason to use multiple partitions is to isolate operating systems from one another when you install more than one operating system on a computer. You can also create separate partitions for different operating systems. Even after the installation you can create or delete disk partitions as per your requirements.
Depending on the hard disk configuration, do one of the following procedures during installation:
■ If an existing partition is large enough, install new OS on that partition. Installing on an existing partition might overwrite any existing operating system files.
■ If the existing partition is not large enough, delete it and combine it with other partitions on the same physical disk to provide more unpartitioned disk space for creating the partition for new OS
Although you can use Setup to create other partitions, you should create and size only the partition on which you will install the OS.
