If I am not mistaken, Windows is the only OS, that uses local time for the system clock (instead of UTC). This means that in multiple boot configurations, every restart of the system into Windows will screw up the system time. In order to reset it (in Ubuntu 16.04), use
sudo timedatectl set-timezone Etc/UTC
I am used to the fact that a Linux installer honours a pre-existing install of Windows and offers to setup the computer with a dual-boot option during installation. Vice-versa no Windows installer honours any other pre-exisiting OS. Therefore I was surprised that when I tried to install Ubuntu 16.04 on my PFSense box (FreeBSD), the Ubuntu installer did not even see that a BSD install exists on the drive. I chose the "erase all" option, but when I rebooted after the installer has finished, the system went straight into PFSense without giving me any option to select Ubuntu.
Since we are operating our Äkta Avant in a multiuser environment, we need to separate the methods and results of the different users.
