Introduction

This page describes how to set up your computer in order to dual boot Ubuntu and Windows.

Before you start

Back Up Your Data

Accidents can and do happen, especially if you have not taken reasonable precautions beforehand. External hard drives, USB flash drives, and multiple DVDs or CDs are useful as external backup media.

Windows Recovery CD/DVD

Before starting to install Ubuntu properly please ensure you have a Windows installer or "Recovery CD" easily available. See here for a guide on how (and why) to do that.

Resizing partitions

You may need to create empty space on your disk. In order to avoid problems:

  • resize Windows partitions with Windows tools
  • resize Linux partitions with Linux tools

Installing Ubuntu after Windows

Usually a Windows is already installed. If not then it 'should' be installed before Ubuntu because Windows cannot see other operating systems and tries to ignore them (or wipe them). The last boot-loader to be installed is the one that gets used and while the Windows one is blind to other operating systems the Ubuntu one defaults to including all other Operating Systems in its boot-menu.

If you are able to partition the drive prior to installing Windows, leave space for Ubuntu during the initial partitioning process. Then you won't have to resize your NTFS partition to make room for Ubuntu later (saving a bit of time).

Please see this guide for information on installing Windows First.

Installing Windows After Ubuntu

Normally when Windows is installed after Ubuntu the "Master Boot Record", MBR, will be overwritten. You can bootup off a LiveCD and repair the MBR. See RestoreUbuntu/XP/Vista/7Bootloader.

Please see this guide for information on installing Windows Last.
