Boot Manager is corrupt or Missing

Ran into problems today.  Was playing an old game when system got hung up.  Rebooted Windows 7 Pro and couldn't reboot.  Ran Startup Repair and got message saying "Startup Repair cannot repair this computer automatically"

Error message was "Boot manager is corrupt or missing"

Other info:   repair action:  file repair
                   Result:  error code 0x15
                   Time taken:  0 ms

I found a posting with a similar problem for Windows Vista but am not sure the same fix would work for Windows 7.   Help!!!!!!!!!!!

Hi WeebleM,

Before following the method below make sure you unplug any external devices attached to the computer except the mouse and the keyboard.

Method 1: Perform System Restore from the installation disc adn see if that can make any difference.

Refer the link below for more information on this;

Method 2: As the the Startup Repair option does not resolve the issue, you must troubleshoot more steps manually, use the Bootrec.exe tool.

Follow the instructions form the link below;

Method 3: See if you can boot the computer to Last Known Good configuration by following the steps below.

1. Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer by clicking the Start button , clicking the arrow next to the Shut Down button , and then clicking Restart.

2. Do one of the following:

·  If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you'll need to try again by shutting down and restarting your computer.

·  If your computer has more than one operating system, use the arrow keys to highlight the operating system you want to start, and then press F8.

3. On the Advanced Boot Options screen, use the arrow keys to highlight Last Known Good Configuration (advanced), and then press Enter.

4. If your computer has more than one operating system installed, use the arrow keys to highlight the operating system that you want to start by using Last Known Good Configuration, and then press Enter. Windows will then resume starting normally.
