boot - Problem reinstalling Ubuntu 12.04 (Dual with Windows 8) - Black Screen

It have been a week since I use Ubuntu alongside with Windows 8. Yesterday I tried to reinstall Ubuntu 12.04 from the CD, I chose the option Erase Ubuntu 12.04.4 LTS and reintall, I followed the installation process as I followed when I installed it for the first time.



When the pc restarts, after reinstallation, I had a Grub problem so I followed the steps from this webpage howtoubuntu.org/how-to-repair-restore-reinstall-grub-2-with-a-ubuntu-live-cd#.UyVs4JDLTIU , I restored the Grub.



The problem came when I try to enter in Ubuntu from the grub, I got a black screen and the message is :




Kernel panic - not syncing : VFS : Unable to mount the root fs on unknown-bloking(0,0)

In this moment I can use Windows 8 normally, I access from the grub.




Thanks in advance for any help you are able to provide.
