I have a Sony VAIO notebook. Years ago a technician installed the Windows XP Media Center Edition 2005 Sony Corporation. I was never given the installation CD. In the last year, I purchased the Home Version of Microsoft Office. When I installed it something happened where I messed up on the installation and now my BOOT MGR is missing. I don't have the CD to reference back to. How do I get the necessary BOOT MGR files for my specific computer? Please help me. My disabled husband works from home on his desktop computer.
