1. Introduction

This document explains how to transfer, or migrate, an entire Linux system, including LILO, from one hard

disk to another.

In the following explanation, /dev/hda (first IDE hard disk) means the old disk, and /dev/hdb (second

IDE hard disk) means the new disk.

Specific partitions on the old disk are referred to as /dev/hda1 , /dev/hda2 , and so on. Specific

partitions on the new disk are referred to as /dev/hdb1 , /dev/hdb2 , and so on.

The explanations in this document are based on Red Hat 6.0. They have also been tested with Debian 2.1,

Slackware 3.5 and SuSE 6.2; we indicate a few differences to note if you're using those distributions.

If the commands don't work properly on your system, please let us know, mentioning what distribution you're

using.

1. Introduction

2. Install both disks on your system

Modern systems can accept four EIDE devices on the hard disk controller, so there shouldn't be any problem

installing both disks on your system at the same time, even if you also have other EIDE devices. Hard disks

and CD−ROM drives are typical EIDE devices. Floppy drives and tape drives are usually connected to the

floppy drive controller rather than to the hard disk controller.

SCSI adapters are even more flexible and can accept seven devices. If you're lucky (and rich) enough to have

a SCSI adapter, you probably already know this, and you probably know which of your devices are

SCSI devices! For more information, see the SCSI How−To.

Even the oldest systems can accept two devices on the hard disk controller, so you can still install both hard

disks at the same time. However, if you already have another device installed in addition to your hard disk

(for example, if you have both a hard disk and a CD−ROM drive), you'll have to remove the other device to

be able to install the old hard disk and the new hard disk at the same time.

You must configure the disks as master or slave by installing the disks' jumpers as appropriate. You'll often

find configuration information on the disks themselves; if not, consult the manuals or the disks'

manufacturers.

You must also inform the BIOS of the disks' presence and of their geometry . Usually, you enter the

BIOS setup program by pressing a key during the system boot−up. Here's what to do for some common

BIOSes:

Acer notebooks

F2 key during Power−On Self−Test (POST)

American Megatrends (AMI)

Del key during Power−On Self−Test

Award

Del , or − − Ctrl − − − − Alt − − − − Esc − − − − − − − −

Compaq

F10 key after the square appears in the top right corner of the screen during boot−up

Dell

− − Ctrl − − − − Alt − − − − Enter − − − − − − − −

DTK

Esc key during Power−On Self−Test

Hewlett−Packard Pavilion

Packard Bell

For some models, F1 or F2 key during Power−On Self−Test

Phoenix

− − Ctrl − − − − Alt − − − − Esc − − − − − − − − , − − Ctrl − − − − Alt − − − − S − − − − − − − − , or −

− Ctrl − − − − Alt − − − − Enter − − − − − − − −

Many older systems require an Installation or Reference Disk.

We're interested in receiving information on other BIOSes to add them to this list.

Reboot the system and login as root. If you use the su command to become the user root, use su − , with the

hyphen option.
