1. Installing Linux

2. Module 1 – Installing Linux ♦ Overview This module introduces you to the hardware and software terminology necessary to install a Linux operating system. The procedure for installing Linux and the necessary configuration settings are described. ♦ Lessons Covered in this module ► Performing Preinstall Evaluation ► Performing Installation

3. Installing Linux Lesson 1 – Performing Pre-install evaluation ♦ Introduction Linux occupies less amount of space in a system. However, running a complete Linux system has certain hardware requirements that are discussed below. ♦ Topics covered in this lesson ► Hardware Compatibility ► Disk Partition Scheme ► Considerations of Dual Boot

4. Installing Linux ♦ The installation of an operating system will have its own hardware requirements. The necessary hardware has to be checked for its compatibility with the operating system before installing it. ♦ The hardware units required for installing Linux includes: ► Central Processing Unit ► Memory (RAM) ► Drives ► Video or Graphics Card Topic 1 – Hardware Compatibility

5. Installing Linux Topic 2 – Disk Partition Scheme ♦ Partitioning is one of the methods employed in securing a system. ♦ Partitioning is dividing a single hard drive into many logical drives. ♦ In case of partitioning a disk, if a file system gets corrupted then only the disk having the damaged file system gets corrupted. ♦ Other partitions will not be affected by the damage caused by a file system.

6. Installing Linux Topic 3 – Considerations of Dual Booting ♦ Every distribution of Linux can be installed on only particular partitions of a hard disk and other partitions can remain untouched. ♦ This ideally implies that Linux permits Microsoft Windows to coexist with it. ♦ To consider a dual boot system for Linux, a computer should have one operating system already installed in it. ♦ This means Linux should be installed last in a dual-boot system.

7. Installing Linux ♦ Introduction Linux can be installed in a system through various methods. On a standalone system, the most convenient method is to install through a CD- ROM drive. Before installing Linux, it has to be ensured that the system meets all the requirements for installation. ♦ Topics covered in this lesson ► Types of Installation Methods ► Starting Installation Lesson 2 – Performing Installation

8. Installing Linux Topic 1 – Types of Installation Methods ♦ There are four methods available to install Linux on a system. They are: CD-ROM Hard Drive Ask Method Kickstart ♦ The installer called anaconda, is written in the scripting language Python

9. Installing Linux ♦ The first thing in installing Linux is booting off from the CD-ROM. ♦ At the bottom part of the screen there will be a prompt, which will read as: boot: ♦ If no key is pressed then the prompt will time out by itself and start the graphical installation process. ♦ There are settings that have to be configured such as keyboard, mouse, disk partition etc Topic 2 - Starting Installation

10. Installing Linux Conclusion ♦ Summary ► Linux can be installed in a system that has other operating systems like Windows ► Minimum hardware requirement has to be met for installing Linux that includes CPU, Motherboard, Drives and Video cards ► Linux can be installed by using several methods such as, CD-ROM, Hard drive, HTTP, NFS and Kickstart ♦ Question and Answer session
