5# Click on “NEXT” button when it will show the “Language to install” and “Time format… Keyboard input method“.

8# Now type “bootrec.exe /FixMbr” without quote and hit the enter key.
Now type “bootrec.exe /FixBoot” without quote and hit the enter key.

Be alert, while typing the commands in the command prompt.
9# Now restart your PC and run again the Bootable CD or Pen-Drive. (You can try without restarting the PC).
Follow the same steps as above and open the command prompt again. (Don’t run the previous commands again)
Now type “diskpart” command without quote in Command prompt.
Now type “list disk” and press the enter key. (This command will show you the list of all available drives of your PC).
Now input the drive number in command prompt window where “Windows” is already installed.
I’m typing “0“, because Windows is installed on “0” number’s hard disk.
Now type “select disk 0” and press enter key. (This command will show you the list of all hard drives)
Now type “select partition 2” and press enter. (If you installed the Windows in Partition 3, then you have to type “select partition 3“. Note: Partition 1 is the reserved memory). Look at the Disk size to identify.
Now type “active” and press the enter key.
Now type “exit” to exit from diskpart.
Now type “RESTART /S” to restart the computer from command prompt.
