Start from a USB drive running Ubuntu, go to the specified configuration folder, check for a backup of the SYSTEM registry in the "regback" directory. Transfer it to the parent location. Rename your current SYSTEM file to SYSTEM.backup. The key issue is identifying why the registry gets corrupted—this usually doesn’t happen on normal systems. Also verify your hardware (RAM and storage device) after this process.
A simpler option exists—connect your storage device to a functioning machine using Explorer.
