Operating Systems

Guide to Operating Systems, 4th ed. 2
Objectives
2
• Explain the overall process of installing and
upgrading operating systems
• Prepare for operating system installation and
understand the factors involved in making the
decision to upgrade
• Install and upgrade the following operating systems
and understand the various options presented in:
– Windows XP, Vista, and 7, Windows Server 2003/R2, 2008/R2,
Linux Fedora, and Mac OS X Leopard and Snow Leopard
• Obtain operating system patches and minor
upgrades through the Internet

Introduction to Installing an Operating
System
• Two types of operating system installations:
– Clean installation – on a computer that either has no operating
system or on a computer that has an operating system that will
be overwritten by the installation
– Upgrade installation – on a computer that already has an
earlier version of the operating system
• Process of installing a new OS varies from one
operating system to another
• Divided into three stages:
– Preparation for installation
– Installation itself
– Any required or optional steps following the installation

System
• Preparing for installation involves:
– Making sure the computer meets or exceeds the hardware
and/or software requirements
– Ensuring that all equipment is powered on and operating
correctly
– Having all OS CDs or DVDs on hand
– Understanding the general features of the OS you are installing
so you can decide which modules to install or omit
– Having DVDs/CD-ROMs or files on a flash drive for any device
drivers that might be needed for new equipment
– Having up to date and accurate information available about
your computer and peripheral devices

System
• During the installation, you may need to provide
some or all of the following:
– Where (in which drive, directory/folder) to install the OS and
what to name the directory/folder that contains the OS
– What type of installation you wish to perform (Custom or
Upgrade)
– Information about you, your company, and your computer
(computer or workgroup name)
– Licensing information verifying your right to install the OS
– Which components of the OS you want to install
• After installation, keep the product key, ID number
or activation number in a safe place

System
• The installation consists of some of the following
general functions:
– Gathering system information
– Loading/running the installation program
– Determining which elements of the OS are to be installed
– Configuring devices and drivers
– Copying operating system files onto your computer
– Restarting the system and finalizing configuration of devices
• Most OSs have the Plug and Play (PnP) feature that
automatically configures internal and external devices
as part of the installation

Preparing for Installation
• Advance preparations:
– The computer must be working correctly
• Defective disk drive, DVD/CD-ROM, or a bad section of memory
can make installation difficult
– Many operating systems try to automatically detect the
hardware connected to your computer
– The result of nonworking hardware can be a failed installation

Checking the Hardware
• Make sure that all external hardware is turned on
and ready for use
– Examples: SCSI devices, printers, modems, and scanners
• Have all available information about your hardware
– Know how many hard drives, what size they are, and the type
of disks (such as SCSI or SATA disks)
• You should also know:
– How much memory you have
– Make and model of your video card, network card, sound card,
etc…
– The types of device drivers for your printer, scanner or other
device

Checking the Hardware

Checking Drivers
• Examples of devices that require special drivers
– DVD/CD-ROM drives, SCSI drives, network interface cards,
printers, and scanners
• Drivers may come on a disk with the device but
might not include drivers for all possible operating
systems
– Check device documentation to see which OSs are certified for
use with particular hardware
• Newer drivers might be available that will make the
device work faster/better
– Go to the hardware manufacturer’s website to download the
latest driver that matches the OS you will be installing

Ensuring Hardware Compatibility
• Many OSs have certain hardware requirements
– Usually found in OS documentation or vendor’s Web site
– Example: Compatibility information for Windows 7 can be found
at the Windows 7 Compatibility Center on Microsoft’s
website
– Red Hat Linux has the Red Hat Certified Hardware program,
which offers manufacturers a software test suite for testing
hardware
– An Intel-based Macintosh is required for Mac OS X Snow
Leopard or later versions
– “Minimum” recommendation usually means that you can install
the OS but you will not be able to use it
• Look for recommended specifications instead of minimum

Migrating to a New Operating System
• Migrating is a term used to refer to move from one
operating system to another, which may or may not
involve implementing a new computer
• Decide whether to perform an upgrade or clean
installation
– Upgrade installation usually costs less and you can select to
retain your existing settings, data files, and applications (saves
time)
– Clean upgrade gives you a fresh start by reformatting the hard
disk, which enables disk problems to be found and fixed
• Takes more time to configure OS, copy back data files and
reinstall applications

• Decide if an upgrade is necessary:
– Will it enable you or your organization to perform tasks or use
software you can’t use now?
– Will it save money in the long run by increasing productivity or
enabling new services?
– It is best not to upgrade/migrate shortly after a new operating
system is released
• By waiting, bugs may be found and fixes made available
– Some OS vendors offer prerelease or beta software to try
• Alpha software – an early development version in which there are
likely to be bugs
• Beta software – software that has successfully passed the alpha
test stage

• Checking Hardware and Software
– Windows XP, Vista, and 7 offer a tool (Upgrade Advisor) that
will check if your system hardware and software are ready for
the new OS
– If your organization supports many computers, consider
keeping an inventory of the hardware (See Table 5-2)
– Keep detailed records of custom software settings (changes in
the defaults)
– Determine what software is used on systems prior to an
upgrade so you make sure it is compatible with new OS
• Perform a software inventory before upgrading (See Table 5-3)

• Backup – copying files from a computer to another
medium, such as tape, DVD, another hard drive, or
a removable drive
• Most operating systems have a backup utility
• Before backing up your information:
– Close all open windows, programs, and files
– Make sure you have the software to restore the backups under
both the new and old operating system
– Make sure you actually make a full backup (not just the boot
disk, but all fixed disks connected to the computer)
– Make sure the new system will be able to read your backup
without problems

Conducting a Test Migration
• If upgrading more than one or two computers, you
should plan to test a migration before applying it to
a production computer
– Choose a computer that represents the lowest memory, speed
of CPU, size of hard disk, etc…
– The test computer should have all the same software and be
fully functional on the same network as the computers that will
be upgraded
– Take notes describing the steps and any problems that arose
and what you did to solve those problems
– Create a written checklist that documents the
upgrade/migration process (See Figure 5-3 in the book)
– Once complete, test the computer for a few days

Conducting a Test Migration
• During the test phase, ask an experienced user to
use the test computer for a few days.
• Ensure that the upgrade did not change any
settings or move/remove files or programs
• These tests can be time consuming
– You may need a week or longer to get through them
– It is better to find out during a test that an OS
upgrade/migration will not work for you
– Test results may also be used to explain to management why
an upgrade/migration should or should not be carried out

Training
• When migrating to a new desktop OS, training is
recommended
• Could be classes, training videos, training DVDs,
etc...
• Training should be offered for server administrators
as well as end users
• There is an initial expense with training, but the
return on investment (ROI) can be worth it
– User productivity should improve as well as user morale

Installing and Upgrading Windows XP
• Windows XP has two versions:
– Home – intended for recreational/home users
– Professional – has more features than Home and is intended
for office and networked environments
• Hardware Requirements:

• Installing Windows XP
– New to XP is the concept of activation. Once you finish setup
you have 30 days to activate your copy of XP (by phone or
online)
– Windows XP has a utility called Files and Settings Transfer
Wizard – allows you to transfer your files from your old
computer to your new one via a cable or network connection
– After installing, use the Windows Update feature to download
and install any critical updates along with any optional updates
• Hands-on Project 5-4 enables you to practice an XP install

• Upgrading to Windows XP
– You can upgrade to XP from the following:
• Windows 98, Windows Me, Windows NT, and Windows 2000
• Upgrade process is identical for Windows 98, Me, NT, and 2000
– Use the option to check system compatibility before you start
• If no incompatibilities or problems were found you can begin
• If there is an incompatibility, stop the upgrade and check with your
computer manufacturer for Windows XP updates
– Upgrade should take fro 30 to 90 minutes to complete
– After you upgrade, use the Windows Update feature for
additional features and special upgrade options

installed on an Intel-based computer

Mac OS X Leopard hardware requirements
Mac OS X Snow Leopard hardware requirements

• Installing Mac OS X
– You can boot a Macintosh computer from the installation DVD
and perform a clean installation of the OS
– Three parts to the installation process: booting from DVD,
running the installer, and restarting from the hard drive
– A Mac will boot from the DVD/CD-ROM drive only if instructed
to do so
• To do this hold down the option key when you turn on the
computer and select to boot from the Mac OS X Installation DVD
– General steps for performing a clean installation are outlined
on pages 264 – 265 in the book

• Apple encourages Mac OS X Leopard users to
upgrade to Snow Leopard by offering the upgrade
at a very low price
• Before attempting to upgrade to Mac OS X Snow
Leopard:
– Use the Time Machine application to fully back up Mac OS X
Leopard

• Hands on Project 5-10 enables you to perform an
upgrade to Mac OS X Snow Leopard

Regular Updates for Operating
Systems
• Every OS vendor provides bug fixes, security patches,
and interim upgrades between major releases of an OS
• Windows Updates
– Windows Update – a Web-based function that allows you to
download and install fixes, updates, and enhancements
– This feature is available on Windows 98 and later versions
• Linux Updates
– Most Linux distributions come with an update module for
obtaining the latest updates
• Mac Updates
– Mac OS X Leopard and Snow Leopard offer the Software
Updates tool to enable you to check for recent updates

Chapter Summary
• There are two basic types of installations: a clean installation and
an upgrade installation. The process varies from one OS to
another, but all installations can be divided into three general
stages: preparation for installation, the installation itself, and any
required or optional steps following installation.
• Before installing or upgrading to a new OS, make sure that it is
necessary. Check that your hardware meets the requirements for
the new OS, and make sure you have the most current drivers for
devices on your system.
• Before you upgrade, make sure that you have a working backup of
the current OS and data. Check your backup after it is made to
make sure that you can perform a restore from it if the install or
upgrade is unsuccessful.

Chapter Summary
• The installations of and upgrades to Windows XP, Windows
Vista, Windows 7, Windows Server 2003/R2, Windows
Server 2008/R2, Linux, and Mac OS X Leopard and Snow
Leopard are overviewed in the chapter text and described
step by step in the Hands-On Projects.
• After installation, and at regular intervals thereafter, it is a
good idea to check for and download operating system
updates. All of the Windows versions described in this
chapter provide the Windows Update tool, Linux provides an
update module, and Mac OS Leopard and Snow Leopard
offer the Software Update tool.
