Second Semester : Lec. 1 : Computer Preparing (Partitioning)
The hard drive is an important part of computer parts, a storage device that provides always saving data even after the power supply interrupted. A partition is an area of a hard disk that can be formatted and assigned a drive letter, (The terms volume and partition are often used interchangeably). Your system partition is typically labeled with the letter C. Letters A and B are reserved for removable drives or floppy disk drives. Some computers have hard disks that are partitioned as a single partition, so your whole hard disk is represented by the letter C. Other computers might have an additional partition that contains recovery tools, in case the information on your C partition becomes damaged or unusable.
How do I create more partitions?
To create a partition or more partitions on a hard disk, you must be logged in as an administrator, and there must be either:
• unallocated disk space(unformatted space that is not part of an existing partition or volume) or
• free space within an extended partition on the hard disk.
If there is no unallocated disk space, you can create some by shrinking an existing partition to create unallocated space.
A boot partition is a partition that contains the files for the Windows operating system (OS folder). If you want to install a second operating system on your computer (called a dual-boot or multiboot configuration), you need to create another partition on the hard disk, and then install the additional operating system on the new partition. Your hard disk would then have one system partition and two boot partitions.
A system partition is a primary partition that contains the hardware-related files and the Boot folder (the boot loader, a piece of software responsible for booting the OS.), these tell the computer where to look to start Windows.
With Disk Management, you can create a maximum of three primary partitions on a hard disk. If you are installing different versions of Windows, you must install the earliest version first. If you don t do this, your computer may become inoperable.
If we want to use the hard drive we must divide it (at least to the one partition) and formatting these partitions.
In fact there are three types of partitioning: the essential Primary, Extended and Logical. The total data storage space of a PC HDD can contain at most four primary partitions, or alternatively three primary partitions and an extended partition. The Primary and Extended are the basic divisions (partitions) of the hard disk, later this extended can be divided into any number of logical partitions.
