Boot Manager is corrupt or Missing

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.

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.
