I was running Hitman Pro on my Sony Vaio laptop, shut the computer down and when I turned it back on, it will no longer boot and goes straight to recovery options menu. It seems that the C drive is no longer recognized, I get a message that states that the OS is not detected on the drive and therefore cannot boot to Windows. What should I do now?

In all probability, your Master Boot Record must have been overwritten, In this case the entire installation goes bad and boot disk is not recognized.
To repair this you need to have the Windows installation disk.
Insert the installation CD and boot your system.
Press F8 while booting to go to the Windows Recovery Menu.
Click on Advance Recovery options.
In this menu click on Automatic repair.
Thereafter go to Command Prompt. And type the following commands :
Reboot the system. Alternatively you could use partition tools to repair boot sectors.
This should have solved the problem.
