Step 3. We can see the partition that saves the system registry (boot is written at the end) from the listed volumes, and then type the following command to copy the necessary registry files from the boot:

xcopy c:\windows\system32\config\regback c:\windows\system32\config

Step 4. This will prompt an overwrite question if it is to all the folders (Default, Sam, Security, Software, and system) or not with an "(Yes/No/All) question. Now type the command "A "for All and click on "Enter". This will copy all the necessary files, and you just need to restart your system now to resume as normal.
