Resolution :

Method 1: Repair the BCD store by using the Startup Repair option

Boot from the vista dvd >> Repair your computer >> System Recovery Options >> Startup Repair >> restart the computer


Method 2: Rebuild the BCD store by using the Bootrec.exe tool

Boot from the vista dvd >> Repair your computer >> System Recovery Options >> Command Prompt >> Bootrec /RebuildBcd

If the Bootrec.exe tool runs successfully, it presents you with an installation path of a Windows directory. To add the entry to the BCD store, type Yes. A confirmation message appears that indicates the entry was added successfully
If the Bootrec.exe tool cannot locate any missing Windows installations, you must remove the BCD store, and then you must re-create it. To do this, type the following commands in the order in which they are presented. Press ENTER after each command.

Bcdedit /export C:\BCD_Backup
ren c:\boot\bcd bcd.old
Bootrec /rebuildbcd
Restart the computer
