The ide drive is /dev/hda, the SATA drive is /dev/sda. The problem is
with GRUB on /dev/hda, it never gets as far as loading the kernel. GRUB
hangs with the message: Loading stage 2. I have been reading the grub
docs, but I cannot find anything relevant. Does anyone know what GRUB is
doing at stage 2? I don't know what kinds of problems could lead to this
error.
