I tried to install Ubuntu 11.10 and 11.04 many times with many different ways but after installation, instead of booting up, there was a blank purple screen. I tried many solutions but none of them worked.

I have an Intel Dual Core i5 3.2 Ghz and a Ati graphics cards.

That is all I know :(

I tried 64 bits and 32 bits but same result... Now I am running Ubuntu 10.04 32 bits. And I know nothing of programming so please try to be clear with your answers. Thanks already!

What are your installation steps? Are you installing it from a cd/usb? Although it shouldn't make a difference I've had many successful installs with cd/dvd than with USB. Given its i5 processor it should support 64 bit. So installing either 32/64 shouldn't matter. – Sunil Mar 9 '12 at 17:28
I installed from an usb + live CD no difference. I choosed erase entire disk option. – anilozlu Mar 9 '12 at 19:32

you have 10.04 installed you can upgrade to the latest version of
Ubuntu by starting update-manager and click the upgrade button
or by terminal open your gnome-terminal paste this command in it

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

typ in your password and wait for it to finish.

if it fails to boot again. you might give a memtest and disk test a try
(post your result after)

Please explain how to do memtest. – anilozlu Mar 9 '12 at 19:31
@user49870 You can do it from your bios. press DEL key on startup and get into your bios and search for memtest. – Sunil Mar 9 '12 at 19:35
And there is no update option at update manager and the commands updates/installs nothing. – anilozlu Mar 9 '12 at 19:35

OK guys, I solved the problem myself. I installed 10.10 so there would be an update choice. Then I updated to 11.04. After using it for a while, I decided to take my chance with 11.10 so I updated again and it worked. Thanks everyone!
