Resolved: windows failed to load because the system registry file is missing or corrupt

The problem is

Windows could not start because the following file (\WINDOWS\SYSTEM32\CONFIG\SYSTEM) is missing or corrupt:

Windows failed to start. A recent hardware or software change might be the cause. To fix problem:

1. insert your windows installation disc and restart your computer.
2. choose your language settings, and click next
3. click "repair your computer"

If yo do not have this disc, contact your administrator system administrator or computer manufacture for assistance.

file: \windows\system32\config\system
status: 0xc0000098
info : windows failed to load because the system registry file is missing or corrupt

In our case your windows is Windows 7

This problem is exactly the file “\Windows\system32\config\system” may be missing or corrupted and the windows is already have a backup for this file all you need is to copy the backup file to the the current one and restart like the following

With the Windows 7 CD or usb Key boot the system.
Open a command prompt in the recovery console. (Shift + F10)
go to file location (may be windows appear in D not C because usually there is 100 MB may be invisible for booting)

cd c:\Windows\system32\config
copy regback\SYSTEM SYSTEM

Reboot the system.

Cpanel Log Konumları

cPanel logs most activity that happens on a server to log files so you can go back and review log entries for problems, instead of having to be on the server at the time of them happening.

This guide will cover the locations of the log files for things such as access logs, Apache web server logs, email logs, error logs, ftp logs, MySQL logs, and WHM logs.
