 * Certain machines have the notorious GRUB Error 21 boot problem. To be investigated further. No known workaround as of now, needs further investigation. Probably we should think about going back to isolinux.
Probably User should upgrade their BIOS isn't a solution, maybe it helps.

  * System configuration (locale, network, etc.)
  * X server configuration
 * Look and feel more like an installed Ubuntu system
 * Provide a framework for advanced features
  * Session save/restore
  * Live USB media
  * Live netboot sessions

== Testing ==

Notes and caveats:

- Log in as 'root' for now
- The boot process asks a few too many questions. This will be fine-tuned as development continues
- X isn't configured yet (but this work is nearing completion). If you can copy in a working xorg.conf, run `/etc/init.d/gdm start` to start an X session

Here you'll find some testcases https://www.ubuntulinux.org/wiki/QAtesting. Feel free to add more cases.

Introduction

Any Ubuntu Cd can also be used as a LiveCd as well as an installer Cd to get a fairly normal working session of Ubuntu. Most other versions of linux (distros), not just Ubuntu, have this functionality on their installer Cd too. http://distrowatch.com

Windows people might be more familiar with the term 'boot cd' or 'bootable cd' but a Live Cd session is typically much more useful because it gives a normal desktop environment and all the normal programs.

A LiveCD session is slower than a proper install running from a hard-drive because the Cd/Dvd-drive is usually a lot slower at read/writes and it's also hard to keep settings between sessions, but see 'persistent image' later.

Reasons for Using a LiveCd Session

LiveCd sessions are good to use for;

  • a quick 'demo' on a machine before installing/upgrading Ubuntu
    • to check the hardware works as expected
    • to see if you like the look & feel of the distro

    • to prepare yourself & your unique hardware if required

  • various repair tasks such as
    • repairing grub after (re)installing Windows as part of a dual-boot
    • resizing partitions to give Ubuntu more (or less) room
    • adding a new partition(s) to your hard-drive for other distros
  • 'showing off' Ubuntu to people on their own machine
  • a safer and faster way of surfing the internet or even other uses of a machine that isn't your own. This is particularly good if you have a usb stick or something to save your data and settings on (see 'persistent image')

Using the LiveCD

See the Getting Ubuntu page for details about downloading the LiveCD. After you get your CD, pop it into any computer and reboot the computer. Ubuntu will load. After you are done, shut the computer down and remove the CD.

Keeping your LiveCD settings

If you want to save your LiveCD session to a USB stick, check LiveCDPersistence

Making a customised LiveCD

If you want to make custom Ubuntu-based Live CD, you should read the LiveCD Customization Howto.

To create a customized live system without starting from an existing Ubuntu CD, see LiveCD Customization From Scratch.

Common issues with a LiveCD

Logging in

You can set a password during a LiveCD session by opening a terminal, and typing in:

$ sudo passwd ubuntu

Text-Mode installation

If your normal installation fails without giving an error message, or if you want to install on a very limited system, you can use the text-based installer instead.
