Ubuntu - making of image CD for Karmic Koala 9.10 version.

Ubuntu is distributed over the Internet as CD image files, called ISOs. Unlike a regular data file, the ISO file cannot be dragged and dropped or copied directly onto a disc. It needs to be burned in a specific way that expands/extracts the image so you have usable files on your disc. To install Ubuntu from a CD, you first need to burn the downloaded ISO image onto a CD. This requires:
  • A working CD/DVD burner
  • An 80 minute (700 Mb) CD
The cheapest "write once" CDs that can only usually be bought in packets of 10 or more tend to be much better for this. DVDs require a higher 'burn speed' which often causes problems. More expensive types of CDs seem optimised for data-storage rather than for booting-up from. Also if the 1st one does not work it hurts a lot less and you often get a spindle to keep your linux CDs on.


95 / 98 / ME / 2000 / XP / Server 2003 / Vista: Infra Recorder

  1. Download and install Infra Recorder, a free and open source image burning program.
  2. Insert a blank CD in the drive and select Do nothing or Cancel if an autorun dialog pops up.
  3. Open Infra Recorder and click the 'Write Image' button in the main screen.
    • Alternatively you can select the 'Actions' menu, then 'Burn image'.  

  4. Select the Ubuntu CD image file you want to use, then click 'Open'.
  5. In the dialog, click 'OK'.

XP / Server 2003 / Vista: ISO Recorder

  1. Download and install the appropriate version of ISO Recorder.
  2. Insert an unformatted CD into your burner. (Note: one can burn DVDs with this tool only from Vista.)
  3. Open Windows Explorer, browse to your ISO file, right-click and choose "Next".

Windows 7

  1. Right-click on an ISO image and choose “Burn disc image”.  
  2. Select a disk burner (drive) and press "Burn".  


The procedure may differ slightly depenting on which version of Ubuntu you are using
  1. Insert a blank CD into your burner. A "CD/DVD Creator" or "Choose Disc Type" window might pop up. Close this, as we will not be using it.  
  2. Browse to the downloaded ISO image in the file browser.
  3. Right click on the ISO image file and choose Write to Disc.  
  4. Where it says "Write disc to" you may have options such as "File image" as well as your CD drive. Choose your CD drive. Your CD drive may show as something like "BD-MLT UJ-210S"
  5. Select the write speed. If you are burning a Ubuntu Live CD (one that you may want to boot from), it is recommended that you write at the lowest possible speed.
  6. Start the burning process.  
  7. After burning completed, verify that your CD contains multiple files and folders and not just the ISO file. This way you will know the process was performed correctly.
