Try to repair Windows Vista, It should work; follow the below steps:
If you are having problems starting Windows Vista, then your first step is to use the automated repair tool called Startup Repair. Startup Repair is a diagnostic tool that can be accessed via the Windows Recovery Environment. In order to start the Windows Recovery Environment you must boot your computer off of the Windows Vista DVD that you purchased or that came with your computer. To start this process, insert the Vista DVD into your DVD drive and turn your computer on. Your computer will start and you should see your BIOS listing your hardware and other information. When that information is cleared, your computer will see that a bootable DVD is inserted and present a prompt similar to Figure 1 below.
As you want to boot the computer from the Windows Vista DVD you need to press a key, and any key will do, on your keyboard when you see the above prompt. After you press the key, you should hear your DVD reader spinning up and then you will see a black screen with a white status bar at the bottom stating Windows is loading files.... After a while, the status bar will turn completely white and you will see a screen stating that Windows is loading. The Windows Setup environment will continue to load and when finished you will be presented with a screen similar to Figure 2 below.
At this screen you should configure the Language to install, Time and currency format, and Keyboard or input method options so that they are set correctly. When done, press the Next button. You will now be at the main Windows Vista setup screen where you would normally install Vista on to a computer.
As we want to repair the computer, you should click on the Repair your computer option. This will bring you to a new screen where the repair process will look for all Windows Vista installations on your computer. When done you will be presented with the System Recovery Options dialog box as shown in Figure 4 below.
Select the Vista installation you would like to repair and if there are drivers you need to load in order for Vista to access any of your drives or other components , then you should click on the Load Drivers button to load them. When ready, press the Next button to continue.
If the repair process does not detect any problems starting Vista, it will display a list of recovery tools. These recovery tools are discussed further in the Advanced Tools Overview section below. As we want to perform an automated repair, we would click on the Startup Repair option under this list of tools. It should also be noted that if the repair process detected that you previously had problems starting Vista, instead of displaying the list of recovery tools, it would have automatically started the Startup Repair tool for you. When the Startup Repair tool starts, it will scan your Vista installation for any problems. If problems are found it will attempt to fix these problems automatically. This automatic repair process can be seen in Figure 5 below.
The automatic repair process can take quite a while. So please be patient as Vista attempts to find and repair any problems on your computer. During this process your computer may reboot multiple times, which is normal and nothing to be worried about. During this process you may also be presented with a dialog box asking if you would like to restore your computer using System Restore.
You should click on the Cancel button at this prompt because there is a better System Restore option that can be used from the advanced tools list which we will cover later. For now, just click on the Cancel button and continue with the Startup Repair process. The repair process will now continue to scan your installation for errors to fix. Once the repair process has completed, if it could not find any problems, you will be given an option to send your information to Microsoft.
When sending this information, it is important to note that you will not receive a response back from Microsoft with a solution. Instead they use this information to determine if this is a bug that a lot of people are having and that they need to rectify or if they need to create a support article on how to fix it. If you wish to send the information, then click on the Send information about this problem (recommended) option. Otherwise, click on the Don't send option. You will now be at a summary screen.
You can now click on the Finish button to reboot your computer to exit the repair process or if you would like to try some more advanced options then click on the View advanced options for system recovery and support. We recommend that you try the advanced tools if the Startup Repair tool could not fix your problems. You can also reach the advanced tools at any time during a Startup Repair scan by clicking on the Cancel button. An overview of the advanced tools can be found with links to their individual tutorials.
