Yes, including swap, and dmesg doesn't report any errors. I chrooted to /mnt/sysimage and tried grub-install /dev/hda1 : Installation finished. No error reported. (hd0) /dev/hda ... but no better result after a reboot (exactly the same messages). My bet is : grub is ok, initrd maybe, but something else is missing (udev ? selinux is disabled).
