This question already has an answer here:
This issue happened spounteniously, i don´t know what could have cause it as i wasn´t using the PC when it happened. I ruled out any messing around with the setting as the user doesn´t know how to enter the BIOS, doesn´t have the sudo password and was only using firefox and libreoffice when it happened.
After the plymouth sequence i get this error.
And this option:
I follow each option and nothing happens after that. The issue persist after rebooting. I choose the other options to see if anything happens, i either get back to option 1 or doesn´t show anything anormal. (I have pictures i someone wants to know)
What i found weird is that event though the error is possitioned in the chip, however ubuntu 10.04 and 12.04 run fine in a live CD
I saw that some people are having issues when LightDM has a non default wallpaper, but i use a default one.
Thanks in advance.
