Windows comes with an in-built “chkdsk” tool to find and repair errors in individual drives. It helps to keep your Hard Drive optimized and fault free. This is a vital step to validate integrity of the corrupt drive.

To initiate this scan, use command prompt as illustrated here:

  • Extend to Advanced Startup options as formerly

Boot files crucial for safe computer startup need to be studied and scrupulously checked to ensure they are neither corrupt, nor missing. Otherwise, the system fails to load and the user is left stuck at the restart loop.

Fortunately, there are powerful Command Prompt commands that scan the vital information stored in Boot Configuration Data (BCD) and repair any corrupt/missing content. To use these commands, follow the steps below:

  • Open Command Prompt from the recovery environment described above
  • Execute the following commands individually:

Bootrec /scanos

This command scans all disks for installations compatible with Windows versions. This command is especially helpful when there are Windows installations that the Boot Manager does not list

Bootrec /fixmbr

This option writes an OS compatible MBR (Master Boot Record) to the system partition. Note that it does not overwrite the existing partition table

Bootrec /fixboot

This instruction writes a new boot sector to the system partition, replacing any corrupt boot sector stopping the startup

Bootrec /RebuildBcd

This option completely rebuilds BCD store, cleaning any corruption previously hosted

Executing the commands with bootrec.exe tool should resolve any corrupt entries found in the startup storage data. Retry logging into your system and see if the issue disappeared. If you are still bullied, continue with the techniques.

Method 5: System Restore

This function reverts any recent changes, manual or automatic made to the crucial system settings. Most often, installing third-party software or proceeding with an incompatible driver update can tamper registry values and adversely affect computer operations. This can be undone by bringing the PC back to its previous working state, adopting previous configuration, and settings.

To execute this method, do the following:

  • Reach Advanced options as before
  • Select System Restore from the available options
  • Follow on-screen instructions to choose a restore point
  • Restart the machine
