Help, Used Norton Power Eraser and now windows will not boot. stuck at ACHI BIOS not installed

Yesterday when I ran Norton antivirus it found some malware on the computer that it said it can't remove.  It suggested me to use Norton power eraser to clean it.  I ran the Norton power eraser and it found couple problems that it said it will fix/delete.  While I was inspecting which file it is planning to delete, I accidentally clicked ok and the process started before I can dis-select some programs that I want to keep and i know it's not the problem.  So I let the power eraser finished and rebooted the computer.  Everything is still working so far.  But then I stupidly decided to run power eraser again and tried to reverse the fix to get my programs back.  After it finished, now the window won't boot up.  It get stuck at the message "ACHI BIOS not installed".  I believe it was stuck there for the whole night last night. I have no idea how to fix this.

 

Any help is appreciated.
