I had a similar issue with an HP server recently and it ended up being 
that grub had somehow selected the wrong  drive as the boot drive.(grub 
starts and then nada like you describe-it ended up being a messed up 
device.map file)  if you don't want to mess with the grub files:
  /boot/grub/device.map
  /boot/grub/menu.lst
I suggest doing a base install on one drive and adding in secondary 
drives later. (it made my life easier-messing with the device.map file I 
tried a few times but something seemed to be missing)
