Answer 1

i couldnt solve the problem with any online guide or answers with similar problems. i reinstalled the ubuntu but still the same problem was there. Then i installed windows 10 by deleting ubuntu partition, logged in with windows 10, accessed my other partition and confirmed that cut,copy paste and delete is working. This time i turned off fast boot, shutdown the system and installed ubuntu by deleting the windows 10 partition. Finally the problem is solved. It was a really frustrating experience.
