I noticed today that my MBR doesn't get a fresh new grub install. I did a
"dd if=/dev/zero of=/dev/sdb bs=512 count=1" and it stays empty, grub never
kicks in. That maybe explain the grub 2 error. I also saw in the install cd
that grub gave me an error message that it can't read the stage1 file. I
tried installing grub manually but I got the same problem.
