I can not upgrade my system from Ubuntu Gnome 15.10 to 16.04 by Software Updater, then I trying download ISO file and burn to disc. I can boot to Ubuntu from it and install 16.04, but the option "Upgrade... to Ubuntu Gnome 16.04 is disabled"upgrade to 16.04 is disabled. I want to keep all data (/usr) and installed program on my computer (eg. Skype, VirtualBox...). What should I do or what is the best option for my case ?

Your best bet would be to upgrade from Ubuntu .. try typing in a terminal the following:
sudo do-release-upgrade -d
If that doesn't work run
update-manager
click on Settings
Look for "Notify me of a new Ubuntu version" and set it so it says "For any new versions"
Then use update-manager to check for updates install any if any new ones show up then check again and it should come up with the upgrade
