Windows failed to start?

January 11, 2010

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…
I would try to do that but my keyboard won’t respond when the screen comes up, so I can’t select anything.

My computer will not boot up unless my Windows XP cd is in the CD-Rom drive.?

I had to do a clean install of Windows XP Pro on my home computer recently and everything went just fine, but it seems that the computer will not boot up unless the Windows installation CD is the in CD-Rom drive. Nothing has changed with my computer hardware wise, and this didn’t happen when I first installed windows on this computer. I’ve tried reformatting and reinstalling but it doesn’t help. Any suggestions would be great!

my aunt asked me to install Windows Vista Home Premium on her comp.,she had XP and it saysWindows Vista capable.When Installing I selected the Upgrade option instead of doing the clean installation. no problems installing,but afterwards everything is running slow. Ibrought the comp.to my house to use dsl &installed all the the windows updates in hopes that it would solve the slowness. When that was done the computer restarted itself &said it was configuring the updates & then when I came back to check on it Windows Boot Manager was on the screen saying:

2. Choose your language settings, and then click NEXT

…File: \windows\system32\winload.exe status: 0xc000000f

When i put the vista or the hp reinstall disc in nothing happens. PLEASE help I really dont want to lose everthing. THANKS.
I can’t get past the Windows Boot Manager, I tried pressing F8 to try and get it back to last known good configuration, but pressing F8 doesn’t do anything. I’d be happy if I could just get back to the XP version so she doesn’t lose any of her programs, and then trying to re-install Vista while connected to the internet.

Brand new Asus model X83V. Had it for about 2 weeks. I turned it off (properly) and left it alone for about 2 hours. When I turned it back on "Windows boot Manager" came up with the following message;

"Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your Windows installation disc and restart your computer.
2. Choose your language settings, and then click Next.
3. Click "Repair your computer."

File: \Windows\system32\kdcom.dll
Status: 0xc0000098
Info: Windows failed to load because the kernal debugger DLL is missing, or corrupt"

I have not installed anything since 2 weeks ago. I do not have a Windows disc. I have a recovery disc, but if I run that I will lose my pictures. My pictures are super important to me. I would lose all the pictures from my daughters birthday, among other important pictures I just can’t lose! Please help!
