Hello,
My Compaq Laptop will not go to my Desktop (Home Screen). Here is exactly what it does, i turn on the power button & it goes to this screen ***We apologize for the inconvenience, but windows did not start successfully. A recent hardware or software change might have caused this etc.*** It ask me if... I want to start windows in safe mode normally (or with Networking or Command Prompt), Last Known Good Configuration (Your most recent settings that worked) or start windows normally. I have tried every one of them but every time I do it checks my D: drive with this CHKDSK & then takes me to this BLUE screen that says....

***STOP: c0000218 {Registy file failure}
The registry cannot load the hive (file):
\SystemRoot\System32\Config\SOFTWARE
