This sounds very much like your root filesystem is damaged, or invalid.
We need to find out where you installed your system to, and wherefrom 
you tried to boot in the 2nd step.

Please
* use rdbinfo or similar tools to read out your RDB (or all of them,
  if youhave more than 1 disk)

* report the kernel startup messages about scsi busses and disks, the ones 
looking like this:

xxx at yyy blabla
scsibus0 at xxx 
sd0 at scsibus0: more information
