You can try to disable SELinux in /etc/selinux/config or in
/boot/grub/grub.conf.

In /etc/selinux/config, change SELinux to DISABLED.

OR

In /boot/grub/grub.conf, add selinux=0 to the kernel line.

E.g. kernel /vmlinuz ro root=/dev/sda2 selinux=0

You shouldn't start X server or login to GNOME as root.
