PC Support & Repair Chapter 5 Windows Installation

Objectives • After completing this chapter, you will meet these objectives: ▫ Explain the purpose of an operating system. ▫ Describe and compare operating systems to include purpose, limitations, and compatibilities. ▫ Determine the operating system based on customer needs. ▫ Install and upgrade an operating system. ▫ Understand & describe the boot process.

The Operating System • OS provides interface between user, application & hardware

OS Terms • All modern OS’s have all of these capabilities Describing Operating Systems Multi-user Two or more users have individual accounts to work with programs and devices at the same time Multitasking OS can operate multiple programs at the same time Multiprocessing OS can support two or more CPUs Multithreading OS can execute different parts of a program (thread) at the same time without interfering with each other

Basic Functions of an OS Manages Files & Folders Controls Hardware Access Provides a User Interface Operating System Manages Applications

Purpose of OS: Hardware Access • Interaction between hardware & application • Device driver handles this ▫ Program from hardware manufacturer • Pn. P auto detects hardware & installs driver ▫ OS then configures the device ▫ Updates the registry

Purpose of OS: File & Folder Management • Folders (directories), subfolders (sub-directories), Files

Purpose of OS: User Interface GUI (graphical user interface) CLI (command line interface)

Purpose of OS: Application Management • Click an icon, OS locates program, loads into RAM • OS makes sure the application has system resources • An Application Programming Interface (API) is a set of guidelines used by programmers to ensure that the application they are developing is compatible with an OS. ▫ Open Graphics Library (Open. GL) – Cross-platform standard specification for multimedia graphics ▫ Direct. X – Collection of APIs related to multimedia tasks for Microsoft Windows ▫ Windows API- Allows old Windows programs to work in newer versions of Windows ▫ Java API- related to Java programming

Review- 4 Q • You are creating a new web design software. What guidelines do you need to follow to ensure it will work on an OS? ▫ API • DOS has what kind of interface? ▫ CLI • Windows has what kind of interface? ▫ GUI • What are the 4 basic functions of an OS? ▫ Hardware access, manage files/folders, user interface, manage applications

Processor Architecture • Amount of data a CPU can handle; How an OS processes data; 32 -bit & 64 -bit OS • 32 -bit (x 86) OS ▫ Can only access up to 4 GB RAM • 64 -bit (x 64) OS ▫ ▫ Can access more than 128 GB RAM Data path is bigger, faster Need 64 -bit program to take advantage of it Backwards compatible with 32 -bit

Desktop OS • Supports a single user • Runs single-user applications • Shares files & folders on a small network with limited security • Windows, Mac OS, Linux ▫ Linux is open-source ▫ Many different versions of Windows & Mac OS

Network OS (NOS) • • Supports multiple users Runs multi-user applications Increased security over Desktop OS Network resources: ▫ Server applications/shared databases ▫ Central file storage ▫ Centralized user acct management ▫ Redundant storage ▫ Network printing

Project • 5. 1. 2. 3 ▫ Search NOS Certifications & Jobs

Customer Requirements for an OS

Pick the Right OS • What’s their budget? • What applications is the customer using? ▫ Will the OS be compatible? • Is it compatible with the existing hardware?

Check Minimum Requirements • • RAM Hard disk drive CPU Video adapter card • May need to upgrade some • Make sure you have more than minimum

Checking OS Compatibility • Verifies your hardware is compatible with the OS ▫ Upgrade Advisor or Assistant

Windows OS Upgrades • Helps remain compatible with newer hardware • Check requirement before upgrading • BACK UP ALL DATA!

Data Migration • 3 tools to transfer data ▫ User State Migration Tool (USMT) �User files and settings �Download from Microsoft ▫ Windows Easy Transfer �Transfers files and settings �USB, CD/DVD, flash drive, external drive, network Professor Messer

Project • Lab 5. 1. 4. 4 ▫ Data Migration in Windows 10 ▫ ONLY TRANSFER PICTURES FOLDER

Review- 2 Q • Before you install a new OS, you should check if your hardware will work with it. What should you reference? ▫ Windows Compatibility Center • Windows & Mac are versions of what types of OS that are designed for a single user? ▫ Desktop OS

Operating System Installation

Parts of the Hard Drive • Sector ▫ Small section • Cluster ▫ One or more sectors • Track ▫ One complete circle of data on one side of a hard drive platter ▫ A track is broken into groups of sectors

Clean Install • When passing on computer to another user • When OS is corrupt • When replacing hard drive • Install from CD/DVD is most common ▫ Must set BIOS to boot from optical drive • During install, you can partition/format a hard drive ▫ This process prepares a file system in a partition for files to be stored

Partition Standards BIOS UEFI • Looks at beginning of 1 st disk • Checks boot sector for MBR • The MBR contains the boot loader ▫ Boot loader knows where OS is stored & how to start it • BIOS doesn’t know about partitions or OS • Smarter than BIOS • Knows about all disks/partitions and installed OSs • Uses a GPT (GUID Partition Table)

Primary Partition • Contains OS files • Usually the 1 st partition • Can be divided into smaller partitions • MBR BIOS drive: Max of 4 primary partitions • GPT UEFI drive: Max of 128 primary partitions

Active & Extended Partition. MBR BIOS Drives Only • Active Partition used to store and boot the OS ▫ Only 1 primary can be marked active at a time ▫ Usually the C: drive • Need more than 4 partitions per drive? • Extended Partition ▫ These are not bootable ▫ Only 1 extended partition per hard drive ▫ Extended can be broken up further into LOGICAL DRIVES �Can be split up to 24 more

MBR BIOS Drive Example 1 st Hard Drive; Bootable; All of the HD is one letter; PRIMARY PARTITION C: C: C: 1 st Hard Drive; C: is PRIMARY bootable; D: is an EXTDENDED LOGICAL PARTITION D: D: E: 1 st Hard Drive; C: is PRIMARY bootable; D: & E: are EXTDENDED LOGICAL PARTITIONS

Disk Types • Basic ▫ Default ▫ Can have partitions • Dynamic ▫ Can create volumes ▫ Change sizes of partitions

Review- 3 Q • If you have 2 MBR BIOS hard drives, how many primary partitions can you have? ▫ 8 • Which MBR BIOS partition has the boot loading files? ▫ Active, usually C: drive • If you have 2 physical MBR BIOS hard drives, how many extended partitions can you have? ▫ 2

UEFI GPT Drives • All partitions are primary • NO active, extended, or logical • Only for 64 -bit systems • Check what format you have: ▫ ▫ Disk Management Right-click on drive…Properties Volume Tab Look at Partition Style
