Hi there , I have i problem! I can't install the Lubuntu 12.10 on my pc.
Here is what i do:
1-enter the CD.
2-restart the computer.
3-it's successfully boot from the CD.
4-i select install Lubuntu.
5-it give me black screen with a listener dash flashing.
6-then lubuntu loading like . . . .
7-some code i can't remember looks like:
Lubuntu
. . . . XXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
8-another black screen.
9-the cursor finally shows up.
10-then the problem it back to the loading screen, like a loop from step number 6 to number 9.
and the screen is doing a sound every time its switching to another screen in the loop, what Frickin me out.

My PC:intel Celeron 2.6GHz,
225MB RAM, SiS 32bit.

Any idea how to install it.
thanx!
