    Sorry I can't do anything as I am not able to access windows . Only BOOTABLE USB and CDs are working .
    Can you manage to migrate the application into the bootable USB? Otherwise I would buy/borrow another drive, clean install and try to unformat your current drive.

    IS THERE ANY DATA-LOSS AT STAKE HERE?

    Cheers

    Noop.
    It has also not worked
    how many partitions do you have into your disk? If you make backup of data you want to store using a Linux live CD or Hiren's Boot and saving data to external HD/USB, then you could try to remove every partition into your primary disk and let windows partition when you choose the installation drive; that should work, but remember to backup data, if any, because that would wipe everithing!

    You stated you ACCIDENTALLY formatted your drive! My simple Q is:

    IS THERE ANY DATA-LOSS AT STAKE HERE?

    Hope this helps.

    Thanks for elaborating on that! Do you make any back-ups of your user(s) data? If so, repartition the drive - to as many as you need - and clean install Windows 10.

    Good luck!

    Thanks for the help but I had alredy seen that and the problem is while selecting upgrade option it says'The computer started using the windows installation media and needs to be restarted.'

    And while selecting custom(advanced) it says ' The windows cant install on this disk. The disk has an MBR partition table . On EFI systems , windows can only be installed to GPT disks.
    When you get to the first screen in Windows setup, press shift+F10 to open a command prompt window. Run the following commands - NOTE this will erase anything left on your hard drive!:

    diskpart
    select disk 0
    clean
    convert gpt
    exit
    exit

    Then proceed with the custom install.
