hi all.. I have a problem. the computer works and everythings fine. but I get annoying massage at the boot prosses in when I start my computer. Error message when you start Windows 7: "The Windows Boot Configuration Data file is missing required information" this is exactly my problem. I tried everything there! but couldn't be able to fix the problem. I noticed that my active partition is a "syster reserved" which means that I have another HIDING partitiion that windows made when I reinstalled windows when the old one crased for no reason.. so, I had windows ultimate (the one that I bought with the computer) and it got crashed and I install a fresh copy of proffesional windows 7. seem that he recovered the old one. but I have windows 7 pro now. thank you.
