Installation cannot proceed

#1
I tried to install Windows Vista RC1 Build 5492 on NAPA system, and it pop up an error message saying that "the computer restarted unexpectedly or encountered an unexpectedly error" on my first restart during installation process. And no matter how many times I re-install Vista, this still occur. I also tried to force the system to enter Safe Mode, but I couldn't complete the installation process in Safe Mode.

:confused:
