"windows cannot verify the digital signature for this file" 0xc0000428

Hi,
I went out and left my pc on, came back hours later and wiggled the mouse to get the pc to come on, nothing happened so i pressed some keys, may of restarted pc, pc boots as normal but a screen comes up saying choose and operating system to start, or press tab to select a tool. i then click on windows 7 home premium ( says recovered in brackets). i then get a long message with status: 0xc0000428, windows cannot verify the digital signature for this file. Cant get out of this screen, what can i do to solve the problem and get my pc back to normal?
