I have tried the grub-install --root-directory=boot --no-floppy hd0 (ou /dev/hda).
Did you already try a simple grub-install (hd0) where hd0 should be the disk that is used for booting and first in BIOS? And the grub.conf should reflect that you have a boot partition (assuming / is on /dev/md1): title CentOS (2.6.18-8.1.8.el5PAE) root (hd0,1) kernel /vmlinuz-2.6.18-8.1.8.el5PAE ro root=/dev/md1 initrd /initrd-2.6.18-8.1.8.el5PAE.img
