Thanks..
I tried the same.. but again.. the system hanged without booting new version. just with blank screen with cursor!

Did you MD5 test the ISO you downloaded?
Did you burn the CD as SLOWLY as possible?

Thanks José Antonio Rey, that solved my question.

Hello..
As per the previous advise, I installed Ubuntu. But again, the system didn't start at all. I used SLOW burning of ISO image but still it didnt work.

What happened exactly ?

I am using Ubuntu 10.04 now. I tried to upgrade to the latest version using Live CD. After the upgrade, the system didn't work. ONLY WITH BLANK SCREEN. I also tried using the " update manager" with the 10.04 but again I got the same problem. In the past days, I tried to use the light versions, XUbnuntu & Lubuntu. But in all of them, 10.04 is working fine and the updated 11.10 not working. I also tried, LinuxMint, which have same code like Ubuntu, but wireless is not detected in that. So, again, I switched back to Ubuntu 10.04.

Could you provide result of command
   sudo lshw -C display
To open a terminal, use Ctrl+Alt+T.

Try "nomodeset".

How to make it?? I am newbie to linux :(

Or try the boot option:

xforcevesa

Explained in https://help.ubuntu.com/community/BootOptions

Thanks.. But unfortunately, it didn't work.!!! Any other suggestion ??

Could try the text installer. May help

It didnt work either.. I am rolling back to XP.
Thanks for your help!

Doesn't the installer in the live-cd offers an upgrade option ! .. try from there .

you could upgrade from command line .. in a terminal . Run

sudo apt-get update && sudo apt-get upgrade

then run

do-release-upgrade

or you do you just wanna wipe it and make a fresh install !

which kernel options have you tried from the live-cd so far !

am not sure how you done it , if you wanna try again from the Live-CD

press tab to enter commands, delete "- -" from the inputline and add "nomodeset"

or instead of " nomodeset "

Try adding

 i915.modeset=1

or

i915.modeset=0

or

acpi=off

press CTRL + X to boot the with the modified kernel.

# see section " Changing the CD Boot Option Configuration Line " in the link below

https://help.ubuntu.com/community/BootOptions

if that got you to the Desktop , and you install as usual , but then after you reboot you still can't reach the installed desktop then do the following :

Reboot and keep your finger on the “SHIFT” key till the grub menu show up. press " e " and

 Highlight the line that starts with " linux " and replace “quiet splash” with “nomodeset” . Hit the " Esc" key then press CTRL + X to continue booting.

Once logged in . run sudo apt-get update && sudo apt-get upgrade

 at this point make sure not reboot before you install and activate your Graphics driver.

So , open the Dash by pressing the super+key .. then go to " System settings -> Additional Drivers "

after that , reboot is required.

I hope i didn't miss any step , if so .. someone should kindly correct me.

Salutation .
