Restoring system using tar boot issues

I am trying to recover my SLES ENT Server 9 from a tar backup. I have successfully restored the MBR and created the paritions and restored the full system using tar. When I try to boot the system after a restart I get the following error:

graphics file (hd0,1) /Message" Missing, press any key to continue"

I hit a key to continue and get the grub boot menu. I try to boot to linux but I get the following error:

Error 15: File not Found

Any ideas I can’t seem to find any information on how to go further.

Thanks
Will
