I just updated my CentOS 6.5 with the following command:
sudo yum update
after the update it asked for a restart and I did it but than now when the loading bar finishes loading I have a totally blank screen and nothing shows. I tried hitting Alt + F1 to access the console but it doesn't work either. Even Ctrl + Alt + del does not restart the server. I have to hard hit the reset button on the server to make it restart. All I am able to access is the GRUB tool when I have the grub option list to load the O.S and than I can hit "c" and have access to Grub console.
I have a second disk in this server where I have ubuntu installed so I am still able to load Ubuntu. From ubuntu I am able to run parted command so "parted -l" shows all available disks, CentoOS is installed in the first one from the list(ATA KINGSTON) I am lost here and not able to recover from this, any help will be very much appreciated:

Update: Whenever I try to mount my CentOS disk from Ubuntu with command:
sudo mount /dev/sda /media/centos -t ext4
I get an error:
mount: wrong fs type, bad option, bad superblock on /dev/sda,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
