      • Open Command Prompt and execute the following commands:

        bash

        Copy code

        bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

  • Check Disk Health:
    • Run CHKDSK:
      • Boot from the installation media, open Command Prompt, and run chkdsk /f /r C: to check and repair disk errors.
    • Disk Health Tools: Use tools like CrystalDiskInfo to check the health status of the disk. Replace the disk if it shows signs of failure.
  • Update Storage Drivers:
    • Device Manager: Boot into Safe Mode or use the recovery environment to update or reinstall storage drivers via Device Manager.
    • Manufacturer’s Website: Download the latest drivers from the motherboard or computer manufacturer’s website.
  • BIOS/UEFI Settings:
    • Verify Boot Order: Ensure the boot device order is correctly set in the BIOS/UEFI settings.
