Appendix B. Installation Howto

This document describes how to install Ubuntu 4.10 “Warty Warthog” for the Intel x86 (“i386”). It is a quick walkthrough of the installation process which should contain all the information you will need for most installs. When more information can be useful, we will link to more detailed explanations in the Ubuntu Installation Guide.

B.1. Booting the installer

For more information on where to get CDs, see Section 4.1, “Official Ubuntu CD-ROMs”.

Some installation methods require other images than CD images. Section 4.2.1, “Where to Find Installation Images” explains how to find images on Ubuntu mirrors.

The subsections below will give the details about which images you should get for each possible means of installation.

B.1.1. CDROM

Download the image for your architecture and burn it to a CD. To boot the CD, you may need to change your BIOS configuration, as explained in Section 3.6.1, “Invoking the BIOS Set-Up Menu”.

B.1.2. Booting from network

It's also possible to boot the Ubuntu installer completely from the net. The various methods to netboot depend on your architecture and netboot setup. The files in netboot/ can be used to netboot the Ubuntu installer.

The easiest thing to set up is probably PXE netbooting. Untar the file netboot/pxeboot.tar.gz into /var/lib/tftpboot or wherever is appropriate for your tftp server. Set up your DHCP server to pass filename /pxelinux.0 to clients, and it with luck everything will just work. For detailed instructions, see Section 4.4, “Preparing Files for TFTP Net Booting”

B.2. Installation

Once the installer starts, you will be greeted with an initial screen. Press Enter to boot, or read the instructions for other boot methods and parameters (see Section 5.2, “Boot Parameters”).

After a while you will be asked to select your language. Use the arrow keys to pick a language and press Enter to continue. Next you'll be asked to select your country, with the choices including countries where your language is spoken. If it's not on the short list, a list of all the countries in the world is available.

You may be asked to confirm your keyboard layout. Choose the default unless you know better.

Now sit back while the installer detects some of your hardware, and loads the rest of itself from CD, floppy, USB, etc.

Next the installer will try to detect your network hardware and set up networking by DHCP. If you are not on a network or do not have DHCP, you will be given the opportunity to configure the network manually.

Now it is time to partition your disks. First you will be given the opportunity to erase and automatically partition either an entire drive. This is recommended for new users, but if you have any valuable data on the disk, be sure to back it up first, as it will be erased!

If you do not want to erase an entire disk, or if you want to customize the partition layout, choose “Manually edit partition table” from the menu, and the next screen will show you your partition table, how the partitions will be formatted, and where they will be mounted. Select a partition to modify or delete it. Remember to assign at least one partition for swap space and to mount a partition on /. Appendix A, Partitioning for Ubuntu has more information about partitioning.

Now the installer formats your partitions and starts to install the base system, which can take a while. That is followed by installing a kernel, then by copying the remainder of the packages on the CD to your hard disk so that you no longer need the CD.

The last step is to install a boot loader. If the installer detects other operating systems on your computer, it will add them to the boot menu and let you know. By default GRUB will be installed to the boot record of the first harddrive, which is generally a good choice.

The installer will now tell you that the first stage of installation has finished. Remove the CD and hit Enter to reboot your machine. It should boot up into the next stage of the install process, which is explained in Chapter 7, Booting Into Your New Ubuntu System.

If you need more information on the install process, see Chapter 6, Using the Ubuntu Installer.

B.3. And finally..

We hope that your Ubuntu installation is pleasant and that you find Ubuntu useful. You might want to read Chapter 8, Next Steps and Where to Go From Here.
