Finally I resolved problem with booting using boot-repair. Error in booting disappeared but after that installation was still incomplete. Any application using Qt5 have not started. It took me a lot of time to resolve this partial installation of Qt :-( Is it be better when the installation of Grub was at the begging of installation or at very end? Why boot-repair logic ins't available during installation process?
