I reinstalled manjaro(in different partition), and now entry is showing in the grub menu(3 entries → 1 windows and 2 manjaro), i performed my commands i mention in topic and now its working fine,
just need to delete the newly installed manjaro partition and grub entry then i will be back to my original setup

thanks @winnie @stephane @linux-aarhus

What a trip, yeah? Even to this day, booting up a system still hasn’t reached the practicality of what an iPhone or Android phone offers: just turn it on and you’re good to go! Glad you got it back to a working dual-boot setup. Hopefully it’ll be smoother going forward since you’re all up to date. For future reference, simple partition layouts (with recent backups of your /home directory) will save you a headache or two down the line.

Thank you for updating us, @sonal! :v:
