Each time you install do you activate the proprietary drivers for your ati card? (installing ati catalyst?) – captain_G Nov 26 '11 at 16:55
This question should instead be filed as a bug report, thanks! Instructions here. – Jorge Castro Feb 3 at 0:33

If you have an external usb drive plugged in, unplug it before booting.

I had the same problem and I "solved" it this way:

  1. start computer and let it freeze
  2. press and HOLD on/off button until you stop computer "hard way"
  3. wait 10s and start computer again
  4. now it boots correctly!

I dont know why it helped. Maybe stopping Ubuntu incorrectly makes it start more safely :-)
