If this error is shown when you boot cent os 6.3
then you should have disabled selinux (linux firewall)
and after that you have rebooted the system.

now reboot the system

when the menu comes that says
	automatic booting in 10 secs.
press 'e' to edit the command
select the kernel
	line starting with kernel.x.x.x
press 'e' to edit kernel command
at the end of the line write
	3 selinux=0
3 is the runlevel for the boot process
and selinux=0 means that we are disables selinux permanentaly

now login as root user

edit /etc/inittab and look for a line that begin with id:5. Replace the 5 in that line by 3
	nano /etc/inittab


    Runlevel 0 and 6: halt and reboot the machine, respectively.
    Runlevel 1: No services running, only root can login.
    Runlevel 2: Users can login but no networking.
    Runlevel 3: Networking and text-mode.
    Runlevel 4: unused.
    Runlevel 5: GUI.
it will add 3 permanentaly in the kernel boot command

now add selinux=0 permanentaly in kernel boot command
by editing /boot/grub/grub.conf
	nano /boot/grub/grub.conf

	On the kernel line, add selinux=0 at the end, eg
	kernel /boot/vmlinuz-2.4.20-selinux-2003040709 ro root=/dev/hda1 nousb selinux=0
