I burned an image (using InfraRecorder to do this, as per the Ubuntu website) this time on the CDRW disk and selected as low a write speed as possible. Once finished I put it in the computer and booted up.
This time it went straight through to the first Ubuntu screen (the one that gives the options 'try Ubuntu without installing', 'Install Ubuntu, 'Check CD for defects' etc.) and I selected English. Thought, great everything seems to be going well until I try and select one of the options whereby the computer pauses for a few seconds and then I get a 'I/O error' message stating somthing very similar to 'Error reading boot disk' and giving a Reboot button to click. This seems to happen whichever option I try and choose.
Do you think that the image hasnt burned properly again, or could it be some BIOS setting or something?
Hi AB80,
It sounds as if you have managed to burn your image OK.
The error message that you mention could be because the Ubuntu installer has difficulty identifying which drive to read in your machine to start up the operating system.
Installation to your hard drive will not take place unless you choose the 'Install' option.
Start by pressing 'F3' to choose your 'UK' 'keymap'. (The default is 'US')
Some modern graphics cards can confuse the linux installers, so continue by pressing 'F4' ('Modes') and choosing the 'Safe graphics mode' option.
Then add the extra boot-up info. as explained below: -
The introductory screen, that you make your choices from, uses the 'F6' ('Other Options') key for choosing extra boot options. When you press the 'F6' key you will see a line of text across your screen. (this is the boot-up instructions for the installer)
You should also see a cursor at the end of the line of text. (If you can't, press the left arrow key and you will see the cursor move through the line of text). Anything that you type on your keyboard at this stage should be added to the on-screen text at the position of your cursor.
Move to the right-hand end of the text and type 'irqpoll' and press the 'Enter' key. The Ubuntu installer will try to install again and may identify your hardware better with this extra instruction.
If that still fails, you can try using the same technique to add 'all-generic-ide' as well as 'irqpoll' which again tries to increase the chances of the installer identifying your hardware correctly.
Try to note any error messages that you see on screen (a digital camera helps here), but hopefully you will see some progress.
If you like the look of the Ubuntu 'LiveCD', you can choose to install it on your system.
Best to do some serious thinking at that stage.
First question to ask is "Have I got any important data on this machine that I don't want to lose?"
If the answer to that question is "Yes", you need to do some backing up before anything is changed to prepare for installation.
There are a few other considerations before installation is started, but you can ask again about those if and when you decide to do it. After all, you can browse the internet, create and delete documents or spreadsheets, etc. from the 'LiveCD'.
Enjoy your 'LiveCD'
John.
