You wont see flag icon on startup screen
The only thing that worked for me was to shut down the computer, turn back on and immediately begin tapping F8 until I saw the safe mode boot screen. One of the options is boot in safe mode with command prompt – I clicked on that and typed: sfc /scannow
After the scan it said one of her registry files had been corrupt and was restored (automatically). After that the computer began working normal – except that now I’m trying to make a back-up DVD and I’m getting an “I/O error …..”
At least the computer is back to normal, try it!
