I recently partitioned my hard drive to create an empty 43 GB drive on my Windows 7 64-bit Compaq Presario.

After the partition was complete, I used the Windows Installer from the Ubuntu website (wubi) to install Ubuntu 12.04 LTS 64-bit.

With my Dual Boot configuration complete, I restarted my computer and chose the partition with Ubuntu installed on it.

The first time it seemed okay until the login screen, where it froze on the login screen with a dotted purple background and a continuous animated drum sound playing.

I rebooted it and the same thing kept happening.

On around the fourth time, Ubuntu booted correctly.

Then, I messed around with it for a bit when I decided I should install Adobe Flashplayer from the Software Centre. It gave me an “unmet dependencies” error.

So I have two problems :

  • Ubuntu only boots about one out of every four times correctly
  • I cant download certain software from the software center, as i get an error message saying the dependecies are not met.

Tell us what kind of graphics are you using? If you are using widely used nvidia, then the driver needs to be updated.Give the following command in the terminal

$sudo apt-get <drivername>-current

Here driver name will be nvidia. Now you need to configure the driver from additional driver in dash home by activating them. And for the second problem.Give the command

$sudo apt-get -f install

And then give

$sudo apt-get update
