Error Code 161 After Flashing BIOS on Windows 7 PC

Hi Experts,
I am having a problem with my IBM ThinkPad. I was trying to install windows 7 on it. So I flashed the bios. But during the time of restarting my laptop the screen shows ERROR code 161, and it denied my access to bios set up. I am fully confused about how to fix it.
Can you do any favor for me?
