Hello, all.
    I do this test:
    =================================
    1:
    A new PC never run grub-install before .
    rm /boot/grub/*stage*
    reboot

    Is OK. Grub can run and can load kernel.


================================

    2
    grub-install /dev/sda
    rm /boot/grub/*stage*
    reboot

    you can see : grub can not load stage2.

========================
I know that : grub load kernel by this way :
         stage1
        /           \
  stage2       stage1.5
                     \
                  stage2

But I don't know : how grub chose one ?
