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 ?
