I freshly installed Ubuntu 12.04 64-bit on my computer with a dual boot of Windows 7.
After installation it asks me to reboot. I do that and, after it reboots, the update manager automatically pops up and asks me to update around 140 things.
The update goes fine and, after it completes, it asks me to reboot.
This time when I reboot, the screen gets stuck at the Ubuntu start screen (The one with Ubuntu written with 5 dots below it) and doesn't do anything for hours.
What should I do?
