Hi Guys! I hope any of you can help me. I am almost in tears. My laptop is running Vista and at one stage I accidentally switched my laptop off, when restarting it gives me a blue screen with the following info: STOP: c0000218 Registry File Failure The registry cannot load the hive (file) \Systemroot\system32\config\SOFTWARE or its log or alternate. It is corrupt, absent, or not writable. Collecting data for crash dump... etc. I have tried to reboot in Safe Mode, same result. There is nothing wrong with the hard drive, I think. I have the original Vista Disk. I have been able to boot from disk and tried the repair function - no joy! The help tutorial on the disk says I can upgrade (even though Vista is already on the system) without losing my data, files and photos! But I am a bit scared. Can I click on "Install" and a "Upgrade" option will appear? I am so scared of losing my stuff. I was one day away from a full back-up of my entire system! Is there a way to troubleshoot this, or can I go ahead? Pleaaaase help, hopefully one of you can help a lady in distress!
