    Hi,

     

    First please try the following methods first:

     

    Method 1: Startup Repair from the Windows Recovery Environment (WinRE)

    ============================================

    1. Insert the Windows Vista installation disc into the disc drive, and then start the computer. 

    2. Press a key when the message indicating "Press any key to boot from CD or DVD …". appears.

    3. Select a language, a time and currency, and a keyboard or input method, and then click Next. 

    4. Click Repair your computer. 

    5. In the System Recovery Options dialog box, choose the drive of your Windows installation (if not existing, skip) and click Next. 

    6. In the System Recovery Options dialog box, click Startup Repair.

     

    Method 2: Rebuild BCD

    ============================================

    1. Put the Windows Vista installation disc in the disc drive, and then start the computer. 

    2. Press a key when the message indicating "Press any key to boot from CD or DVD …". appears.

    3. Select a language, a time, a currency, and a keyboard or another input method, and then click Next. 

    4. Click Repair your computer. 

    5. Click the operating system that you want to repair (if not existing, skip), and then click Next. 

    6. In the System Recovery Options dialog box, click Command Prompt. 

    7. Type Bootrec /RebuildBcd , and then press ENTER. 

     

    Method 3: Use the Windows Recovery Environment (WinRE) to run System Restore

    ============================================

    1. Insert the Windows Vista installation disc into the disc drive, and then start the computer. 

    2. Press a key when the message indicating "Press any key to boot from CD or DVD …". appears.

    3. Select a language, a time and currency, and a keyboard or input method, and then click Next. 

    4. Click Repair your computer. 

    5. In the System Recovery Options dialog box, choose the drive of your Windows installation (if not existing, skip) and click Next 

    6. At the System Recovery Options Dialog Box, click on System Restore.

    7. Follow the System Restore Wizard instruction as usual and choose the appropriate restore point.

    8. Click Finish to restore the system.

     

    If the issue persists, I suggest focusing on rescuing your important data on your system partition.

     

    You can three ways to recovery your data:

     

    1.    Run Step 1 to Step 6 again of Method 2 again to Enter Command Prompt. Then you can use Dos commands to copy your important on the system partition to other partitions or an external hard drive.

     

    2.    Install a new system (Windows 98/Me/2000/XP/2003/Vista/2008) on another partition. Then you can boot into this new system and access your important files.

     

    3.    Unplug the hard drive from the computer and plug it into another working computer as a slave drive. Then you can access your important files on that computer.

     

    Hope it helps.
