Fix or Repair the corrupted Vista Bootloader in a dual-boot configuration
Windows Vista no longer starts after you install an earlier version of the Windows operating system in a dual-boot configuration.“If you install an earlier version of the Windows operating system on a Windows Vista-based computer, Windows Vista no longer starts. In this case, only the earlier version of the Windows operating system starts.“
Why This Occur ?
These issues occur because earlier versions of the Windows operating system are incompatible with the new Windows Vista startup method. Windows Vista uses a new Boot Configuration Database (BCD) store. This store contains a boot menu and all the information about operating systems that are installed on the computer. Therefore, a Boot.ini file that is from an earlier version of the Windows operating system cannot be used to start Windows Vista.
How to Resolve the Issue ?
Use Bootsect.exe to restore the Windows Vista MBR and the boot code that transfers control to the Windows Boot Manager program.
To do this, type the following command at a command prompt:
Drive:\boot\Bootsect.exe /NT60 All
In this command, Drive is the drive where the Windows Vista installation media is located.
Note The boot folder for this step is on the DVD drive.

He forgot to tell all you people out there who are running pirate copies of vista that if you do as above (which does work by the way)you will have to reactivate your copy of Vista because this process overwrites all of the activation cracks and puts Vista back to an original 30 day trial. It does not make any difference if you are running the pre activated DELL or ASUS version or whatever,even legal microsoft versions will need to be re activated. So be carefull guys.
