Kindly help.

@Prashanta_Mahato I did the installation based on the above link. See if you can install on a Clean OS as mentioned in the article. I formatted my machine and reinstalled macSierra. (How to Clean Install macOS / OS X Without a USB Drive) How to Clean Install macOS / OS X Without a USB Drive

You are highly recommended to start with a fresh machine here unless you are a mac wizz in which case you won’t need this instruction to begin with.
