Hi all,

First of all i'd like to apologize about my english I'd try to explain my problem crearly.

Im trying to install Ubuntu 10.04 LTS on a laptop, the instalation end without any problem.
I did some installations in my system and reboot the laptop, was in that point when the system was unable to reboot, the starup process is blocked in a black screen. I'll explain below how i did to try to fix it.

- I got my system restarted usin Ctrl + Alt + f1
- I installed the privative version for the ATI Radeon HD 2400 graphic card because as far as i know that could be the source of the problem
- The system, again, was not able to restart
- After some restarts usin Ctrl + Alt + F1 the system is not able to restart an a very ugly error appears

What could be the problem with this laptop??

kind regards and thanks in advance
