Without any disks there, grub is saying "here is my disk on (hd0,0) and away I go" And since hd0,0 is the right disk, away it goes. With the other disks there grub is saying "Well, I have two disks, (hd0,0) and (hd1,0). I'm told I need to boot off (hd0,0) and away I go" But, in reality, your main system disk is what grub thinks is (hd1,0) and so it's booting off the wrong disk.
