  1. Logging-in to MCS Linux
    • If the machine is powered-off, please turn it on.
    • If machine is on the Windows login screen, press Ctrl-Alt-Del and the press the drop-down menu on the red power-off button (bottom right) and select Restart.
  2. On the BIOS boot screen, select MCS Linux
  3. Software updates may need to be applied - this may take some time.
    • If the workstation needs to reboot after updates, should boot back into MCS Linux automatically.
