Missing Operating system

hi, guys:
I am a beginner for Suse, and I tried to install Suse Linux 10.1(I got
from APC magazine) into IBM xserias 205 server(3 HDs as raid 5). I
installed completely and no error. The system asks for reboot. After I
reboot, I got Missing Operating system on the screen. I trid to reboot
from CD and try to repair, everything seems ok until it give me red
error, says, system crashed.

I also tried to install this liunx on a PC with Winxp pro already
installed. It couldn't do that even with creating partition.

Any ideas, guy?
