Selecting the Operating System at Boot

Using the boot menu

When the boot menu is enabled (the default), it appears for a short time at startup. The user selects the operating system to start:

  • Windows — the default operating system.
  • Citrix UniconOS (formerly eLux 7) — the UniconOS system installed alongside Windows.

If no selection is made within the menu timeout, the device starts the default operating system. This also applies in an emergency: if Windows is compromised, the user can boot UniconOS from the menu.

Setting the default operating system

By default the device boots Windows. To change which operating system the device boots by default, run the installed command-line tool as administrator after installation:

UniconOSDualBoot.exe boot-menu --default windows
<!--NeedCopy-->
UniconOSDualBoot.exe boot-menu --default uniconos
<!--NeedCopy-->

The tool is installed at %ProgramFiles%\UniconOSDualBoot\. The selection persists across restarts until it is changed again.
