I had the same problem but before installing, on forst dvd boot. Use -x to get to your system and -v to boot seeing the logs so you can figure out what is going wrong.

I have now an installation using iAtkos 5 but my internal (yes, internal) keboard/trackpad doesn't work so i must connect USB keyboard/mouse pair

Also the sleep/shutdown/restart isn't working properly

i have a dell vostro 1500
