If you're using grub as your boot loader, you can use the update utility in Ubuntu 14.04 to migrate. That's all pretty straight forward, as Ubuntu 16.04 will reinstall grub 2 anyways.

The upgrade to Ubuntu 16.04 will not effect your windows boot, the windows boot option will be added to the grub menu, so you can boot into windows by just selecting that.

Until Ubuntu 16.04.1 release, you have to do in by typing in terminal do-release-upgrade -d and it will upgrade you to 16.04 (development distro) but the do-release-upgrade without -d switch which is the general upgrade command to upgrade from LTS to LTS, will take effect after 16.04.1 release, may be sometime in July. You can wait for that or you can do it now because after upgrading to 16.04 (developemant version), you can easily upgrade to 16.04.1 by just running in terminal:

sudo apt update && sudo apt -y full-upgrade
