The first boot stages should happen with the the machine bios loading 
grub, then the kernel and initrd. It sounds like you aren't even getting 
that far.  The usual driver/controller mismatch results in the kernel 
still being loaded by bios, doing it's device detection, then failing 
because it can't mount the root partition. Is the disk you are trying to 
boot part of a raid? And maybe the wrong half?
