How to fix windows failed to start

Hello,
I am currently using Windows Vista Ultimate 64 Bit
Here's my problem:

So earlier, I shut down my laptop, and it said it is updating, so I let it update. Later, I turned my laptop back on, and it said:
A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.
If you have a Windows installation disc, insert the disc and restart your computer. Click "repair your computer," and then choose a recovery tool.
Otherwise, to start windows so you can investigate further, press the ENTER key to display the boot menu, press F8 for Advanced Boot Options, and select Last Known Good. If you understand why the digital signature cannot be verified and want to start Windows without this file, temporarily disable driver signature enforcement.
File: \Windows\system32\winload.exe
Status: 0xc0000428
Info: Windows cannot verify the digital signature for this file.
ENTER=Continue
ESC=Exit

When I pressed Enter, it said "Choose an operating system to start, or press TAB to select a tool:
Microsoft Windows Vista

To specify an advanced option for this choice, press F8.

Tools:
Windows Memory Diagnostic
Enter=Choose
TAB= Menu
ESC=Cancel

I have no disk or anything. When I clicked Enter (to Choose Microsoft Windows Vista) it popped up the previous black screen. And I can't go on to Windows AT ALL. When I clicked F8 to boot into Safe Mode, there was a beeping sound for like 30 seconds, then it said CD ROM Drive (or something like that) and Notebook Drive. And when I click on both of them, it bought me back to the previous black screen. What to do?!
I can't find Safe Mode, or anything. All I can do is just stay on that black screen. Please please please help! Is there something I can do without booting my laptop up, or something I can do with another laptop? Cause I really can't go on my Windows Vista anymore!!!
IDK WHAT TO DO! PLEASE PLEASE PLEASE HELP!
I have another laptop!
PLease help!! Can you please tell me what is causing this problem, and how to fix it?
