Bootmgr is missing

I am continously getting "bootmgr is missing" on my computer which is loaded with Windows Vista. I have downloaded this Vista copy directly from the microsoft website and havent made a copy of the installation disk. This is the real Vista operating system that I am using. Can anyone tell me how do i get rid of this problem? Thanks.

You can try to repair the BCD store by using the Startup Repair option. You can use the Startup Repair option in the Windows Recovery Environment to repair the BCD store. To do this, follow these steps:

1. Put the Windows Vista installation disc in the disc drive, and then start the computer.
2. Press a key when you are prompted.
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, and then click Next.
6. In the System Recovery Options dialog box, click Startup Repair.
7. Restart the computer.

If the previous method does not resolve the problem, you can rebuild the BCD store by using the Bootrec.exe tool in the Windows Recovery Environment. To do this, follow these steps:

- Get your Vista installation DVD and pop it into your drive.
- Then restart your computer.
- Press a key when you are prompted.
- Select a language, a time, a currency, and a keyboard or another input method, and then click Next
- Click Repair your computer
- Click the operating system that you want to repair, and then click Next
- In the System Recovery Options dialog box, click Command Prompt
- Type bootrec /rebuildbcd and then press ENTER

• If Bootrec runs successfully, it will present you with the 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 Bootrec 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 shown below: (Remember to press ENTER after each command)

bcdedit /export C:\BCD_Backup

ren c:\boot\bcd bcd.old

bootrec /rebuildbcd

- Restart the computer
