I saw it on my friend's laptop when the laptop is booting and this screen below appears ,
the device doesn't complete booting until he put a password
can any one help me if he knows the way ?

You have to re-install and perform full disk encryption (LUKS). You will then be prompted to enter a password when you boot.
You could use a bios or grub password
That thing needs Full Encryption enabled when u install Ubuntu...It can be done only at install..If you want it, reinstall Ubuntu... Though it has its own disadvantages in backups or restoring etc...
