12.04 - 3.2.0-29.46-generic-pae kernel boot problem

After updating my kernel to 3.2.0-27 I had problems getting into the system. It was working with the 3.2.0-26 though. I deleted the new kernel and everything was working fine until I started to have the same problem with the 3.2.0-26 too, after a minor update.

Every time I was getting a black screen and when I was force shutting down the PC the error message Broken pipe could be read for a fraction of a second. Then I thought maybe the new kernel was fixed and searched for an update and I saw the 3.2.0-29, which has the same problem.

I read some other posts with similar problems and, it's not from any nVidia driver nor ATI, I have the default VGA driver. The only option on booting up the system now (with any other kernel) is entering "Recovery mode" and then simply "resume" to normal boot which is unpleasant since I have to stay at the PC until the system boots up.

Still not working after running boot-repair. This is what I got in the terminal:
