Hi Marco!

I am suspicious that the fact that you CAN boot into single user mode
means that the grub is fine.  I would guess that X is your problem.

The following to try:

1. Let the machine boot as far as it will go.  Then try an CTL+ALT+F1
.  Hopefully you will then see a login terminal.  If not boot in using
a live CD and establish a terminal. There examine /var/log/messages -
/var/log/Xorg.0.log - and anything else that comes to mind as you look
at those two.

2. Run fsck on the disk.  If you see a lot of errors consider wiping
and reloading the disk.

Good Hunting!

Tod
