Linux Preparation

Instructions :


	STEP 1: When you format a computer hard drive, you
	will lose everything that is on the drive. Therefore it is very important to back up anything you might later want.

	STEP 2: In order to format a secondary drive you will
	need root access. All commands used used in this tutorial are run from a command line (terminal) as root. You may also to make note of the size (total capacity in MB) of the drive.

	STEP 3: Linux refers to hard drives as either “hdx” or “sdx” where x is a letter,
	starting with a, which represents the order in which the drive was added to or detected by the computer. The “hd” prefix is used for IDE and PATA (formerly just ATA), and the “sd” prefix is used for SCSI, SATA, and USB drives. Usually a number is also put at the end of “hdx” or “sdx” to denote different partitions on the same phisical drive, but for the purpose of formatting you only need to know which letter the drive you want to format is.

	STEP 4: The examples given in this how-to are for a computer with two IDE hard
	drives attached as a master and slave. In this, the drives are “hda” and “hdb.” You will need to determine the letter of drive you want to format for your own setup. We will be formatting the drive hdb. For all examples, replace “hdb” with whatever your drive designation is.

	STEP 5: You can see all the drives attached to you system by typing the command
	“ls /dev/hd” or “ls /dev/sd” depending on which type (IDE, SATA, etc.) the drives are. On the example system the result of this command looks like “/dev/hda /dev/hda1 /dev/hda2 /dev/hdb /dev/hdb1” The operating system is installed on hda, which has two partitions (hda1 and hda2), and there is one partition on hdb and hdb1.

Installation :

The most common method of installing Linux on a personal computer is by booting from a CD-ROM that contains the installation program and installable software. Such a CD can be burned from a downloaded ISO image, purchased alone for a low price, obtained as part of a box set, or in a few cases shipped for free by request. A box set may also include manuals and additional proprietary software. Mini CD images allow Linux to be installed from a disk with a small form factor. Linux also offers a more convenient method of installation by allowing users to download CD image files ISO and then the user can use a CD/DVD burning software to create installation CD's/DVD's themselves.

As with servers, personal computers that come with Linux already installed are available from vendors including Hewlett-Packard and Dell, although generally only for their business desktop line.Alternatives to traditional desktop installation include thin client installation and running directly from a Live CD. In a thin client installation, the operating system is loaded and run from a centralised machine over a network connection. In a Live CD setup, the computer boots the entire operating system from CD without first installing it on the computer's hard disk.On embedded devices, Linux is typically held in the device's firmware and may or may not be consumer-accessible.
