Operating System Installation
A clean operating system installation is performed under the these situations:
• When a computer is passed from one employee to another
• When the OS is corrupt
• When the primary hard drive is replaced in a computer The installation and initial booting of the OS is called the operating system setup.
Partitioning
Partitions are the specific areas in which a hard drive is divided. Each partition is a logical storage unit that can be formatted to store information. During the installation process, most operating systems automatically partition and format available hard drive space.
Partitions
Primary Partition
Extended Partition
Active Partition
This partition normally uses the remaining free space on a hard drive or takes the
place of a primary partition. There can be only one extended partition per hard drive, but it can be subdivided
into smaller sections called logical drives.
This one is used to boot the computer. Only one primary partition per disk
can be marked active. In most cases, the C: drive is the active partition and contains the boot and system files.
This primary partition is usually the first one. It cannot be subdivided into smaller sections.There can be up to four primary partitions per hard drive.
LogicalDrive
BasicDisk
DynamicDisk
A dynamic disk creates volumes that span across more than one disk. The size of the partitions can be changed after they have been set. Free space can be added from the same disk or a different disk.After a partition has been extended, it cannot be shrunk without deleting the entire partition.
A logical drive is a section of an extended partition. It can be used to separate information for
administrative purposes.
A basic disk (the default) contains primary and extended partitions, as well as logical drives. A
basic disk is limited to four partitions.

Hard Drive Formatting
This process prepares the disk to accept the new file system. The file system provides the directory structure that organizes the user’s operating system, application, configuration, and data files.Windows operating systems use one of these file systems:
- New Technology File System (NTFS) - This system incorporates more file system security features and extended attributes than the FAT file system.
- File Allocation Table, 32 bit (FAT32) - This file system is used by Windows XP and earlier OS versions.
File Sytems
- The preferred file system type for a clean installation of Windows is NTFS.
- NTFS can support more and larger files than FAT32 and also provides more flexible security features for files and folders.
- exFAT (FAT 64) is a multimedia file systems created to address some of the limitations of FAT, FAT32, and NTFS when formatting USB flash drives, such as file size and directory size.
- Compact Disc File System (CDFS) is a multimedia file system created specifically for optical disk media.

Installation Methods
A custom installation of Windows 7 can save time and provide a consistent configuration across computers on a large network. Windows 7 has several different types of custom installations:
- Network Installation. Requires all setup files to be copied to a network server
- Preboot Execution Environment (PXE) Installation. Uses a PXE boot program and a client’s network card to access the setup files
- Unattended Installation. Uses a network distribution point that uses an answer file
- Image-based Installation. Uses Sysprep and a disk-imaging program, such as ImageX, that copies an image of the OS directly to the hard drive with no user intervention
- Remote Installation. Downloads the installation across the network. The installation can be requested by the user or forced on to a computer by an administrator.
System Recovery Options
When a system failure occurs users can employ the following recovery tools:

After the Windows installation
copies all the necessary OS files to the hard drive, the computer reboots and prompts the user to create a user account. To complete the installation, it is necessary to:
- Install Windows update.
- Use device manager to locate problems and to install the correct or updated drivers.

Authentication refers to the process through which users enter a username and password to access a user account. Windows OSs use Single-Sign On (SSO) authentication, which allows users to log in once to access all system features versus requiring them to log in each time they need to access an individual resource. User accounts allow multiple users to share a single computer, with each user having their own files and settings.

The System Recovery Options are a part of the Windows Recovery Environment (WinRE):
- Startup Repair. Scans the hard drive for problems and automatically fixes missing or corrupt system files.
- System Restore. Uses restore points to restore Windows system files to an earlier point in time.
- System Image Recovery. Creates a system image that replicates the system drive.
- Windows Memory Diagnostic. Examines computer memory to detect malfunctions and diagnose problems.
- Command Prompt. Opens a command prompt window where the bootrec.exe tool can be used to repair and troubleshoot startup issues for Windows.
During the installation, the following data is provided:
- Language to install
- Standards and formats that define currency and numerals
- Keyboard or input method
- Physical location of the installation
- Username and computer name
- Password for the administrative account
- Product key
- Time and date settings
- Network settings

An Automated System Recovery (ASR), for example, the ASR Wizard creates a backup of the system state, services, and OS components. It also creates a file containing information about the disks, the backup, and how to restore the backup. After the basic disk information has been restored, ASR installs a basic version of Windows and begins restoring the backup created by the ASR Wizard.
Some computers that have Windows 7 pre-installed from the factory contain a section of the disk that is inaccessible to the user. This partition, called a factory recovery partition, contains an image of the bootable partition created when the computer was built. This partition can be used to restore the computer to its original configuration.
