Ubuntu 8.10 Installation Problem

[adityaravi1990]

I have a computer with a 40 GB HDD. Its pretty old. I freed up a 10 GB partition to install Ubuntu into it. As the usual procedure, I booted from the CD drive and tried to install Ubuntu 8.10 supplied in the Digit DVD (of course burnt into another CD). Installed everything in the default settings and into that 10 GB space.

Everything went well. But when I tried to boot into Ubuntu the following happens:
After entering Username and Password, the screen goes orange and after that no response is obtained.
This happens everytime I boot into Ubuntu. I reinstalled it 5-6 times, but the same happens.

Can somebody help

And I forgot to tell:

My system meets the requirements to run Ubuntu 8.10.
