Windows 10 Repair Command Prompts: Simplified Guide

I. What are the Windows 10 system repair commands? how to use?

Users have the option to utilize different system repair commands within the command prompt window (cmd.exe) in order to successfully repair their system. Below are some of the frequently used system repair commands that are available.

Before understanding the system repair command, we can understand the steps to open the command prompt window:

Find the “Search” button in the bottom left corner of your Windows 10 device. Type (cmd) into the search box and the “Command Prompt” application will appear on the page. Right-click on the command prompt and choose (run as administrator) to open the Command Prompt window.

1. System file scan and repair command

If you want to scan and repair system files, you can directly enter the (sfc /scannow) command in the command prompt window. The repair process may take a long time, please wait patiently.

Click on sfc /scannow command for more information.

2. Rebuild BCD and repair MBR commands

If Windows fails to start, it may be necessary to rebuild the boot configuration data and repair the master boot record file. In the command prompt window, try running the following commands one by one to fix the MBR and rebuild the BCD. Once the repair is finished, restart the computer to see if it can start normally.

● bootrec /fixmbr

● bootrec /fixboot

● bootrec /rebuildbcd

3. Check disk error command

Disk errors are a common cause of system failures in Windows 10. To effectively address these failures, one can check for disk errors. Simply enter the (chkdsk /r) command in the command prompt window and chkdsk will scan the hard disk for any logical errors or bad sectors. If a bad sector is detected, chkdsk will automatically repair it, but this may result in data loss. For instance, if we want to check the C: drive, we can enter (chkdsk /r C:) in the command prompt (where C: represents the drive letter).

4. Commands to scan and repair system files and system image files

scan system image file command

Enter the (Dism /Online /Cleanup-Image /ScanHealth) command in the command prompt window to scan all system files and system image files to check for damage.

You can also use the command (Dism /Online /Cleanup-Image /CheckHealth) to verify the integrity of the system image file. This will determine if the image is in good condition, if it can be repaired, or if it needs to be discarded and started over. If the image is repairable, you can use the /RestoreHealth parameter to restore it.

repair image command

If the scan image command determines that the image can be repaired, the /RestoreHealth parameter can be utilized to restore the image. This can be done by using the mounted image as a repair source for an offline image. To do so, simply enter the following command at the command prompt: Dism /Image:C:\offline /Cleanup-Image /RestoreHealth /Source:c:\test\mount\windows.

Alternatively, if you want to fix your online image without relying on Windows Update, you can use your own sources by entering the following command at the command prompt: Dism /Online /Cleanup-Image /RestoreHealth /Source:c:\test\mount\windows /LimitAccess. If you are unfamiliar with how to use these sources, you can learn more about them here.
