2. Connect Media:

   • Connect the bootable media to your PC.

Booting into Recovery Mode

1. Restart and Access Recovery Mode:

   • Restart your PC and press keys like F8, F1, or Shift + Restart from the Start menu to enter the Windows Recovery Environment.

2. BIOS Boot Manager:

   • If necessary, access BIOS Boot Manager and select the Windows installation media to boot from.

3. Language Preference:

   • Choose your language preference and click "Next".

4. Install and Repair:

   • Select "Repair your computer" at the install now screen.

Recovery Mode Actions

1. Troubleshoot and Command Prompt:

   • In Recovery Mode, select "Troubleshoot" then "Advanced option" and open "Command Prompt".

2. Identify Drive Letter:

   • Type diskpart and press Enter, then list vol to display all drives.
   • Note the drive letter for your USB or DVD (e.g., G).

3. Locate Installation Files:

   • Exit diskpart by typing exit.
   • Type dir G:\sources (replace G with your drive letter) to confirm the presence of install.wim or install.esd.

Repair System Using DISM Command

1. Run DISM:

   • Depending on your file type, run DISM to repair the Windows image using installation media as the source.
   • Use command:

     dism /image:C:\ /cleanup-image /restorehealth /source:G:\sources\install.wim /limitaccess
     

   • Replace C and G with your specific system and media drive letters.

2. Specify Scratch Directories (if needed):

   • Avoid overloading the system drive by specifying scratch directories:

     dism /image:C:\ /cleanup-image /restorehealth /source:G:\sources\install.wim /scratchdir:G:\ /limitaccess
     

3. Handling Errors:

   • Double-check paths if you receive errors like "Source files could not be found."
   • Verify drive letters and media integrity.

Final Steps

1. System File Checker (SFC):

   • Run SFC to ensure all system files are repaired:

     sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
     

2. Restart PC:

Your Windows system should now be successfully repaired and functioning normally.
