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!
