Failure to show login screen after forced restart (Same with safe mode

My Dad was using one of my 64 bit PCs when a program froze up and he decided to force restart the computer (Pro move, I know). Now I restart and am unable to get to the login screen. Using both safe mode and normal mode gives me the same result. After I choose one of those options, I see the "Windows is starting" message and the icon. However, before I can get to the login screen the screen goes black and all I can see is the curser in the middle of the screen. I would like to be able to get to the login screen so I can access my computer. Any help with this problem would be greatly appreciated as a lot of my work material is on this machine.

Choose boot in last known good configuration.

I dont' see that option. All I see are "Safe Mode" "Safe Mode with Networking" "Safe Mode with Command Prompt" and "Start windows normally"

Hold f8 on bootup. sorry forgot to say.
