Centos – grubby fatal error: unable to find a suitable template

I'm trying to fix my system after moving it from one server to another. It works perfectly with kernel booted via network, but not from the disk.

Reinstalling stock CentOS 6.6 kernel shows this error:

grubby fatal error: unable to find a suitable template

My /boot/grub/grub.conf file looks fine:

default=0
timeout=5
    title linux centos6_64
    kernel /vmlinuz-2.6.32-504.8.1.el6.x86_64 root=/dev/sda3  ro crashkernel=auto SYSFONT=latarcyrheb-sun16 LANG=pl_PL.UTF-8 KEYTABLE=pl
    root (hd0,1)
    initrd /initramfs-2.6.32-504.8.1.el6.x86_64.img

All files are in place:

/etc/fstab looks fine too:

    cat /etc/fstab

devpts          /dev/pts        devpts  defaults        0       0

How to resolve this ?
