Windows failed to start?

Question

So I tried to install a game demo, which finished then asked me if i wanted to restart the computer, so I did. When it starts up it says:

Windos failed to start. A recent hardware or software change may be the cause. To fix the problem:

1. Insert your Windows Installation disc and restart the computer

2. choose your language settings, then click Next

3. Click "repair your computer"

File: \Windows\System32\drivers\sfsync.02.sys

Status: 0xc0000428

Info: Windows cannot verify the difital signature for this file.

If I put in my Vista disc then it comes up with another screen asking If I want to run in Safe mode, run normally etc.

My keyboard won't work on this screen so I can't select anything!! What do I do? I really don't want to have all my stuff wiped so please help...

Hi,

Push F8 continuously when you start up computer, choose line: "last good know configuration..."

If not, push F8 continuously when you start up computer & choose Safe mode, uninstall that game.
