After doing a complete registry backup and then a registry restore using GFI Home, my windows 7 (64 bit) machine will not boot from the hard drive. After the startup POST, I only get a blank screen.
I am able to boot to a Windows 7 rescue disk and have tried running the Startup diagnostics and doing a system restore to yesterday's system restore point but with no luck.
I have run the Windows Starup Diagonostics several times. Most of the time it returns 'no problems found - successful boot' but occasionally it returns 'bad or corrupt boot manager - successfully repaired'. In no case will windows then boot.
After it passes the bios screen the hard drive will flash once and the screen will go blank.
Can someone help me with replacing the startup files manually through dos or do I need to restore the operating system to day one?
Thanks in advance for your help.
