Introduction
Any computer system has an operating system. The user
interacts with the machine via the operating system.
An operating system (OS) is the software that provides
an interface between the computer hardware and the
application programs or users. An operating system is
responsible for the management and coordination of
activities and sharing of the resources in computer. The
OS acts as a host for application programs that are run
on the machine. As a host, one of the purposes of an
OS is to handle the details of the operation of computer
hardware. OS offers a number of services to application
programs and users. Users may also interact with the OS
by commands or using a graphical user interface (GUI).
There are various types of operating systems, but all
of them essentially perform the same functions. This
Unit gives an overview of operating systems. Common OS
include Microsoft Windows, Mac OS X, and Linux. The
installation process of Microsoft Windows 10 and Ubuntu
Linux operating system is illustrated in this Unit. This will
enable the students to gain fundamental knowledge and
skills required to install and configure Windows 10 and
Ubuntu Linux operating systems.

4Introduction to Operating System
Introduction
As you know that, CPU is the main processing unit
of a computer. It processes the data based on the
instructions received. Even for a simple calculation, it
performs a series of instructions. Also, operating the
several peripheral devices attached to, the computer
requires executing certain instructions. The computer
system has several resources such as a CPU, memory,
storage devices, and network devices. All these resources
are accessed by several users and several programs. The
CPU manages all these resources.
A computer also requires a basic user interface to
interact with the user and provides consistent support
to the processor, memory, and devices. An operating
system (OS) is a software that satisfies all these needs of
the user.
In this Chapter, we will discuss the components of
operating system, the different types of operating systems
and the functions of operating system. A brief description
of some operating systems is also given.
Overview of Operating System
A computer cannot perform any tasks on its own. In any
computing process, both the hardware and software
work together to accomplish a task. This applies to all
the computing devices, including basic calculators,
watches, mobile devices, and any other gadgets which
use hardware components as well as integrated software
components. Different files which are interrelated and
accomplish a certain set of tasks make up the operating
system. These files are system level files which do
scheduling, interrupting, data transferring, managing
the flow of data, and are a low level software component
of the computer itself. The standard definition of an
operating system would be—an operating system is a
set of program files which control the resources of the

computer system and allows the communication of
hardware components of a computer to the software
components of the computer system.
An operating system is one of the essential and
important software installed in every computer. A
computer is useless without an operating system. The
operating system is like a resource manager. It controls
and manages all the computer resources including
hardware and software. Computer system mainly has
four types of resources. These are CPU or processor,
main memory or RAM, secondary storage, and the input
output devices.
Booting Process of Operating System
When you start the computer, it is observed that some
initial text information is displayed on the screen. This
is displayed by the firmware. The booting instructions
are stored in ROM (read‑only memory). Then the booting
process starts. After booting, an operating system gets
loaded in the main memory (RAM) of the computer. Let
us understand the complete booting process.
• When you power on the computer, the CPU
(central processing unit) activates the BIOS (basic
input output system).
• The first program activated is POST (power on self-
test). Using the CMOS (complementary metal oxide
semiconductor) memory it checks all the hardware
and confirms that they are functioning properly.
• After that it reads the MBR (master boot record)
in boot drive in accordance with the firmware
‘bootstrap loader’ which is provided by the
computer manufacturer.
• Then the computer loads in the operating system
in boot drive to the RAM.
• Once this is performed, the operating system takes
over the control of the computer and displays an
user interface to the user.
Functions or Tasks of the Operating System
The operating system is a large and complex software
consisting of several components. Different components

of OS perform specific tasks to provide overall
functionality of the operating system. Figure 4.1 shows
the interconnection between resource management in
the computer.
Operating system is a large and complex software
consisting of several components. Each component of
the operating system has its own set of defined inputs
and outputs. Different components of OS perform
specific tasks to provide the overall functionality of the
operating system.
The main functions performed by the operating
system are as follows:
I/O Management
Input/Output (IO) is the basic
process in any computing
device. OS manages I/O
devices and makes the I/O
process effective. It allows
interaction with I/O devices
using commands. OS accepts
inputs from the input device,
stores it in the main memory,
asks the CPU to process it,
and finally, provides the result
to the output device.
Data Management
In a computer, the data or programs are stored in a file.
The data is managed by performing various operations
on a file such as creating, updating, reading, writing,

storing, and deletion. These tasks are performed by
using the commands of the operating system. Thus, the
operating system functions for data management.
Memory Management
Every computer has a primary memory (RAM). This
memory should be managed properly for efficient
functioning of the computer. Operating system loads
the data and programs into RAM before sending it to the
CPU for processing. The results obtained after processing
are also stored in RAM
before sending it to the
output devices. After
sending the output
to output device, OS
releases the memory and
makes it available for
use to other programs.
Thus, operating system
utilises the RAM
efficiently to manage the
memory for various processes. The activities of memory
management are—allocate memory, free memory,
re-allocate memory, and keep track of memory usage.
Process Management
Every job to be performed by the computer system is
scheduled in the form of processes. These processes are

managed by the operating system. Allocation of a CPU
to the processes and making the CPU free when the
process is executed is also performed by the operating
system. The process management activities handled by
the OS are:
1. control access to shared resources like file,
memory, I/O, and CPU,
2. control execution of applications,
3. create, execute, and delete a process (system
process or user process),
4. cancel or resume a process,
5. schedule a process,
6. synchronisation, communication, and deadlock
handling for processes.
Device Management
Operating system manages the
peripheral devices attached
to the computer system. The
processes may require certain
devices. Operating system finds
the status of the device and
allocates the appropriate device.
Device controllers are used to
control the peripheral devices
and device drivers are used to
control software components.
The device management tasks
handled by OS are:
(1) open, close and write the device driver;
(2) communicate, control and monitor the device
driver.

File Management
Every computer system consists
of a large number of files. A user
has to access these files whenever
required. Operating system
performs file management.
File management includes
storage and backups of the files,
accessing files, handling files
and their properties, performing
file operations. Location of the
file, size, its uses, and status
are maintained by the operating
system. Whenever a process
requires a file allocation, then the
file is searched and it is allocated
to that process. Whenever the
process is completed, then the file allocation is removed.
Operating system also prevents the file from viruses
or unauthorised access. The file management tasks
include:
1. create and delete files,
2. provide access to files,
3. allocate space for files,
4. keep back-up of files,
5. secure files.
Time Sharing Management
Computer network allows the use
of the computing power of the
server to a number of users through
network operating systems. In network
environment, each user is allocated a certain
amount of time to access the hardware.
This access time is moved from one user to
another user very fast so that every user has
a feel to access the computer for all the time.
This time sharing management between the number of
users of the computer hardware is performed by the
operating systems.

Security Management
In this, the security of one user is protected from other
users. Operating system provides security to the data
and programs of the user. User authentication, file
attributes like read, write, encryption, and back-up of
data are used by OS to provide basic protection.
Deadlock Prevention
In a multi-programming environment,
multiple processes may try to access the
resource. A deadlock is a situation when a
process waits endlessly for the requested
resource which is being used by another
process that is waiting for some other
resource (Figure 4.9).
Virtual Storage
In a multiprogramming system, many
programs are located in the memory
along with the operating system. Some
applications require large memory as
the whole program cannot be loaded
into the memory. If the program is
larger than the main memory, then the
operating system uses free space of
the secondary memory which is known
as virtual memory and the secondary
storage used for storing which is
known as virtual storage. Virtual
memory allows the execution of those
processes that are not completely in
the memory.
Providing User Friendly Interface
One of the important functions of the operating system
is to provide the user interface. The user interface is a
set of commands or a graphical user interface through
which the user interacts with the applications and
the hardware. There are two types of user interfaces
provided by the operating systems. They are:

1. command line interface – CLI
2. graphical user interface – GUI
Command Line Interface (CLI)
The CLI has a command prompt from where you can issue
a command. The CLI accepts the text based commands
on the command line or terminal and
executes them. In CLI, the correct syntax
of commands has to be used, hence the
commands need to be remembered by the
user. CLI was used by the operating system
of the early days. Operating systems—DOS
and Unix are the examples of CLI. In using
command line interface, the correct syntax
has to be used.
Graphical User Interface (GUI)
The modern operating systems such as
Windows, Linux, and Mac all use GUI.
GUI is easy to operate and user-friendly.
GUI provides the ability to use the mouse
or fingertips to navigate the commands.
It becomes easy to interact with the
computers. The operating system with GUI
uses four components to interact with the
system. These are abbreviated as WIMP
(windows, icons, menus, and pointer).
Types of operating systems
Operating systems are normally preloaded on the
computer that you purchase. But it is possible to
upgrade or install the operating system on your
computer. There are three most common types of
operating systems—Microsoft Windows, Mac OX, and
Linux. For mobile devices, such as smartphones and
tablet computers, the commonly used operating systems
are Apple iOS and Google Android.
Microsoft Windows
It is a graphical user interface (GUI) based operating
system. A typical desktop image of a computer system

Fig. 4.12: Graphical user interface (GUI) screen
Unit 2.indd 74 09-Oct-19 9:59:42 AM

on which a Microsoft Window 10 is installed is shown in
Figure 4.13.
In this GUI system, all the programs
or commands of the operating system are
available in the form of icons, buttons, and
menus. Everything within the operating
system is clearly displayed on the screen
by making a combination of graphics
and text. Whenever we want to execute
any command or program, then the
corresponding icon needs to be clicked.
There are various versions of Microsoft
Windows OS available. Most recent
version of Microsoft Windows OS is Windows 10, which
was released in 2015. The earlier versions are Windows
8, released in 2010, and Windows 7, released in 2009.
Microsoft Windows is one of the most popular operating
systems.
Mac OS
It is an operating system that is created by
Apple. It is a preloaded OS on Macintosh
computer or Macs. A typical image of a
Mac desktop is shown in Figure 4.14.
Observe that this operating system also
has a graphical user interface (GUI). But
the GUI of Mac OS is different from that
of Microsoft Windows. All the commands
and programs available in Mac OS are
displayed in the form of icons or buttons.
By clicking appropriate buttons, we can
execute that program.
There are various versions of Mac OS. Most recent
version of Mac OS is OS X which is pronounced as OS
10. The latest version released on 24 September 2018
is Mac OS 10.14 and is named as Mojave (Liberty). The
earlier versions of Mac OS are OS X 10.11: El Capitan
(Gala) released on 30 September 2015, OS X 10.10:
Yosemite (Syrah) released on 16 October 2014, OS X
10.9 Mavericks (Cabernet) released on 22 October
2013, OS X 10.8 Mountain Lion (Zinfandel) released

on 25 July 2012, and OS X 10.7 Lion
(Barolo) released on 20 July 2011.
Linux
It is a family of open source operating
systems. It means that it can be modified
and distributed by anyone around the
world. Earlier OS that we have discussed
such as Windows and Mac OS are
proprietary software. It means that they
can be modified only by the company
that owns it. Whenever you want to use
proprietary software on your computer
system, you need to purchase it by
paying a cost so that you can get a user
license. Linux is a freeware, meaning
that you need not to pay any cost and
you can use it on your computer system.
A typical desktop image that runs Linux
is shown in Figure 4.15. Observe that
Linux is also available in the form of
GUI. Every program in the Linux OS is
displayed in the form of an icon, button,
or graphics. By clicking on the icon or
button, we can execute that program.
There are many distributors of Linux, for
example Ubuntu, Linux Mint, Fedora,
Suse, Red Hat, and so on.
Classification of OS
Operating systems can be classified based
on the following:
Classification based on
Processing Method
Multi-programming OS
In this, two or more programs are executed
simultaneously by a single processor. It is
used in a multi-user environment.

Multitasking OS
It is capable of running several tasks or
programs at the same time. Most of the
present operating systems like Microsoft
Windows, Linux, and Mac OS are
multitasking operating systems.
Multiprocessing OS
It supports running a program in more
than one CPU. Two or more processors
(CPU) are used to control the different
activities or execution of many program
instructions simultaneously. Servers are
designed to support multiple processors.
UNIX is an example of multiprocessing
OS.
Time-sharing system
In this, the processor is shared among
many users. The CPU switches so rapidly
from one user to another, that every
user gets the impression of getting the
services of CPU for all the time.
Multithreading OS
This has the ability to divide the process
into sub-processes known as threads
and execute them concurrently. Threads
are individual processes that execute
simultaneously in multi-tasking OS.
Batch processing OS
In this, similar jobs are grouped together
for processing. It consists of programs,
data, and system commands. The time
taken between job submission and job
completion is very high. It is suitable for
programs with large computation time
where user involvement is not necessary.

Online processing
operating system
In this, transactions are
processed immediately
and output is provided
to the user. Most of the
present systems use
online processing. Bank
transactions are an example of online processing
system.
Real-time OS
This method receives data, processes it, and returns
results quickly to affect the functioning of the system at
that time. It is an online processing system where the
processing time is critical. Monitoring and controlling
nuclear power stations, rocket launching systems, are
examples of real time systems.
Classification of OS based on User Interface
As we have already learned, there are two types of
user interface. One is command line interface (CLI)
and other is graphical user interface (GUI). The
operating system is also classified on the basis of
user interface.
Classification of OS based on Mode of User
Under this classification, the OS is classified as single
user or multi-user.
Single user OS
The majority of small microcomputer based systems
have single user OS, which allows a single user to
operate the machine in an interactive mode. It allows
only one user program to use the system. MS-DOS, PC-
DOS are single user operating system.
Fig. 4.22: Single user OS
Unit 2.indd 78 09-Oct-19 10:00:01 AM

Multi-user OS
A multi-user OS allows two or more users to run
programs at the same time. The multi-user OS shares
computer resources among these users, allowing each a
small slice of the processor time. This concept is known
as time sharing. Example of multi-user OS are UNIX,
LINUX.
Components of Operating System
We identify the operating system by its user interface.
The look or initial screen of various operating systems
looks different, but architectural view of the various
operating systems remains the same. There are
essentially three components of operating system as
described below:
1. the device driver
2. the kernel
3. the shell
The Device Driver
This component is close to computer hardware. The
device drivers are required for proper functioning
of the devices attached to the computer system.
These drivers can be installed or uninstalled as
and when required. The kernel uses it for operating
and controlling.

The Kernel
It is the core of the operating
system. It performs all the
major functions of the operating
system. It manages resources,
controls program execution, and
schedules program execution. It
is the main operating system. It
detects the new hardware when
attached and installs the device
driver for it to function properly.
The Shell
We identify the operating
system by how the shell looks. It provides the user
interface to interact with the kernel and hardware.
There are two types of user interface— command line
interface (CLI) and graphical user interface (GUI) as
explained in the Chapter earlier.
The File System
The operating system provides a file system interface
to secondary storage. A file system contains files and
directories (folders). Directory is a container that
may contain files and other directories known as
subdirectories. A file is the basic unit secondary data
storage on computers. Any data is stored in a file in the
file system. The file has two components, file name and
extension. File system that is stored on the disk may
have a large number of files and/or directories. Every
file system starts with a root directory.

5Installation and Configuration of
Windows 10
Introduction
Windows 10 operating system is available for many devices
such as phones, tablets, laptops, and desktop computers. It
is also available in multiple editions and in both 32-bit and
64-bit versions. First, one needs to choose the appropriate
editionandarchitectureofWindowstoprovidethenecessary
features, such as Secure Boot, Client Hyper-V, Cortana,
and others. It is also important to verify the compatibility
of existing hardware such as printers, scanners, and other
peripherals with Windows 10.
In a new computer, a clean installation of Windows
10 is the perferred option. For a new computer, the user
needs to select another appropriate installation option
as per their requirements. This installation will resolve
startup and shut down problems as well as memory
usage and app issues. Also, you can get rid of viruses
and other types of malware, fix system corruption, and
improve battery life.
Windows 10 System Requirements
Today’s modern computers are capable of installing
Windows 10. However, if you wish to check the hardware
requirements of old computers, check the minimum
hardware requirements as follows:
1. processor: 1 gigahertz (Ghz) or faster processor
2. memory: 1GB RAM for 32-bit or 2GB RAM for 64-
bit
3. storage: 16 GB of disk space for 32-bit or 20 GB
for 64-bit
4. graphics card: DirectX 9 or later with WDDM 1.0
driver
5. display: 800x600 pixels
It is also recommended to have an internet
connection to download and install updates.

Windows 10 Upgrade or Clean Installation
It is possible to upgrade Windows 10 on the existing
computers or you can choose the clean installation.
If you have the licensed copy of Windows 7, then it is
possible to upgrade it to Windows 10. You can choose
any one of the following three methods for upgrading to
Windows 10:
Inplace upgrade: The existing operating system can
be updated to Windows 10 without destroying the user
data and settings. It is the recommended and most
preferred method for most of the users who wish to
upgrade to Windows 10 in the existing hardware. In
this method, Windows 10 setup program automatically
retains the settings. It is important to backup user data
files before starting the upgrade to avoid possible data
loss. A procedure for inplace upgrade is as below:

Notes
Unit 2.indd 85 09-Oct-19 10:00:04 AM

86
Memory: The 64-bit versions of Windows 10 can
address more physical memory than 32-bit versions.
32-bit versions are limited to 4GB of RAM, whereas 64-
bit versions have no such limitation.
Security: Features such as Kernel Patch Protection,
mandatory kernel-mode driver signing, and Data
Execution Prevention (DEP).
Client Hyper-V: This feature is only available on 64-bit
versions of Windows 10.
Performance: The 64 bit processors can handle more

General features
The following general features of Windows 10 provide
general usability and functional improvements:
Client Hyper-V: enables to create, manage, and run
virtual machines. For this feature, you should have a 64-
bit version of Windows 10 Pro or Windows 10 Enterprise
edition, a computer that supports SLAT, additional 2
GB of physical memory to support running the virtual
machines.
Cortana: you can use Cortana as a digital assistant to
control Windows 10 and perform tasks such as writing
email, setting reminders, and performing web searches.
Since Cortana is voice-activated and controlled,
Windows 10 device requires a microphone.
Continuum: Windows 10 is available on a variety
of devices types and form factors. With Continuum,
Microsoft endeavors to optimise the user experience
across device types by detecting the hardware on your
device and changing to that hardware. For example,
Windows 10 determines when you are using a non-touch
desktop computer and enables traditional interaction
with the operating system by use of a mouse. For users
of hybrid devices, such as the new Microsoft Surface
Pro, when you disconnect a keyboard cover, Windows
10 switches to tablet mode. When you use Windows 10
Mobile, Continuum enables you to use a second external
display and optimises app behaviour on that display.
Notes
Unit 2.indd 86 09-Oct-19 10:00:04 AM

After you have installed and launched Quick Heal
Total Security antivirus, activate it and scan your
computer with this antivirus.
Run a full system scan
After installing and updating the antivirus software,
start a full system scan process. Some antivirus software
programs have different types of scanning and you have
to run the most important type, known as full system
scan. Scanning will take time depending on the disk
size and data size. During full scan, you can continue
any of your other work.
There could be a situation that the antivirus may not
detect any virus or malware while an user is working on a
computer. In such case, it is suggested to run a full system
scan as shown in Figure 5.33 and 5.34 and any viruses
may be removed.
Review discovered threats and recommended action
During the scanning process or after completing
scanning, the antivirus program will inform you about
the various discovered threats and suitable action to be
taken. Although the recommended action will be the best
option, but you can take any action from the available
choices. If the antivirus is not able to remove any type of
infection, then just search for a proper solution on the
internet or ask a professional, don’t ignore the problem.
You can also contact the support team or customer care
of the antivirus software.

Unit 2.indd 105 09-Oct-19 10:00:19 AM

106
Malware
The antivirus program may also has an anti‑malware
program too. If not, then install an anti‑malware
program and check the system again for any
malware infection. Antivirus and anti‑malware both
programs scan for different things but they work in a
similar way.
In the worst case, if you are unable to clean your
computer from virus or malware or not able to repair
the damaged operating system files, then take backup
of important data and format the system. Reinstall
the operating system and application programs. After
reinstalling it, first, install the antivirus software
program and update the antivirus immediately. After
updating, perform the full scan of the system including
backup data.

follow the steps below:
• put the Ubuntu bootable disk in case of DVD into
optical/DVD drives and in case of USB flash drive,
into the USB socket. Make sure the boot device
order has set to the disk being used as either CD/
DVD or USB flash drive.
• restart the computer. After restarting, the
computer will boot from the bootable DVD and
the install window as shown in
Figure 6.1 will appear on your
computer screen.
There are two options shown,
‘Try Ubuntu’ and ‘Install Ubuntu’.
The first option ‘Try Ubuntu’
allows you to just use the Ubuntu
on a trial basis without permanent
installation; the other option
‘Install Ubuntu’ allows actual
installation. It will launch the
installer automatically, as shown
in Figure 6.1. After selecting the
‘Install Ubuntu’ option, select the
language from the left side pan. By default, the language
selected is ‘English’. Ubuntu can also be installed in
other listed languages.
Prepare to Install Ubuntu
Now the installer will recognise your computer

If it doesn’t correctly guess the
default layout of any device,
use the ‘Detect keyboard layout’
button to run through a brief
configuration procedure. The
English (US) keyboard is selected
by default in the keyboard layout
option as shown in Figure 6.3.
Press ‘Continue’ to apply. The
next window will appear as shown
in Figure 6.4, that will ask you
the type of installation—‘Normal
installation’ or ‘Minimal installation’.
The normal installation is
the default bundle of utilities,
applications, games, and media
players — a great launchpad for
any Linux installation. The minimal
installation takes considerably less
storage space and allows to install
the required stuff. Select the
normal or minimal as per your
requirement. Generally normal
option is selected by the beginners.
Below are the other options,
the two checkboxes ‘Download
updates while installing Ubuntu’
and ‘Install third party...’.
It is recommended to tick both
the options. Stay connected to the
Internet to get the latest updates
while the installation takes place.

system then you can install
the Ubuntu alongside the other
operating systems, so that you have
the option to boot the computer
with any of the operating system.
The ‘Erase disk and install Ubuntu’
option will format the hard disk and
start the installation of Ubuntu. In
this case all the previous data will
be lost. If you are an advanced user
choose the ‘Something else’ option.
Select the appropriate option
and click on continue. The next
window as shown in Figure 6.6 will
allow you to review the partition and
allocate the disk space. Change the
partition as per your requirement
and click on ‘Install Now’ button.
In any Linux system, there
should be three partitions namely,
swap, boot, and root (/). If you
keep the pre‑existing partitions as
it is, click on ‘Install Now’ button
to proceed the installation with
pre‑existing partitions. The alert
will be displayed. Then click on
‘Continue’ button to continue the
installation.
Ifyouhavetocreatethepartitions
manually as per your requirement,
then click on the ‘Change’ button
to change the partitions. The ‘Edit
partition’ window will be displayed
where you can create the partition.
First, we will create the swap
partition. Swap is a small space on
the drive that is used like system memory (RAM). It is
recommended to keep the swap area slightly more than

installation are only offered when pre-existing installations are detected.

the amount of RAM in your PC. For example, having
1 GB of RAM creates swap area of 2GB (2048 MB) as
shown in Figure 6.7. When you click ‘OK’ an alert will
be displayed. Then click on ‘Continue’ button as shown
in Figure 6.7 to create the partition name ‘swap area’.
A new partition is created with swap area of 2048
MB as shown in Figure 6.8. Next to create ‘/’ boot
partition, use Ext4 journaling file system as shown in
Figure 6.9.
To create boot partition, select ‘boot’ from dropdown
of ‘mount point’. Also, note that the file system which
Linux uses is selected by default as Ext4. Click ‘OK’ to
create ‘/boot’ partition.
Then create ‘/home’ partition, use Ext4 journaling
file system as shown in Figure 6.10.
Then you will need to create ‘/’ partition, Using Ext4
journaling file system as shown in Figure 6.11.

Begin Installation
After creating the partitions as above, the new partition
table along with the storage space allocated to each
area will be seen as shown in Figure 6.12. To begin
installation, click on the ‘Install Now’ button.
Clicking on ‘Install Now’ button, a small pane will
appear with an overview of the storage options you have
chosen as shown in Figure 6.13. You have the chance to
go back by clicking on the ‘Go Back’ button if the details
are incorrect.

Fig. 6.14: Select your geographical location
Click ‘Continue’ to fix those
changes in place and start the
installation process.
Select your location
If you are connected to the
internet, your location will be
detected automatically. Check
if your location is correct and
click ‘Forward’ to proceed. If
you are not sure of your time
zone, type the name of a local
town, city, or use the map to
select your location.
Change login details
Enter your name and the installer will automatically
suggest a computer name and username. These can
Unit 2.indd 114 09-Oct-19 10:00:21 AM

be changed if you prefer. The computer name is how
your computer will appear on the network, while your
username will be your login and account name.
Next, enter a strong password (Figure 6.15). The
installer will let you know if it’s too weak. You can
also choose to enable automatic login and home
folder encryption. If your machine is portable, it is
recommended to keep automatic login disabled and
enable encryption. This should stop people from accessing
your personal files if the machine is lost or stolen.
If you enable home folder encryption and you forgot
your password, you won’t be able to retrieve any personal
data stored in your home folder.
Background installation
The installation will now complete in
the background while the installation
window teaches you a little about how
wonderful Ubuntu is. Depending on
the speed of your machine and network
connection, installation will take a few
minutes.
