    NOTE:If you are unable to select the USB drive, ensure that the Enable USB Boot Support option is enabled in the BIOS.
  13. Enter the BIOS password if prompted. The default password for most Dell thin clients is Fireport.
    The thin client boots and a warning message with a 60-second countdown window is displayed.
    • Wait for 60 s or Click OK to install the ThinOS image and application packages. The thin client reboots automatically.
    • Click Manually to display the ThinOS image and application packages list. Select the ThinOS image and the application packages that you want to install and click OK to install these files. The thin client reboots automatically.
  14. The system continues imaging and reboots automatically once complete.
    NOTE:If a Login denied (ThinOS activation license is not available) message is displayed in the ThinOS login window, go to ThinOS Activation Licenses.
    NOTE:If the message is not displayed, the system is likely to have a license embedded in the BIOS. Or, the network is configured to automatically configure the Wyse Management Suite information and the device already has a TAL.
    NOTE:If you see the error Fatal Error: Please make sure TPM or PTT is set to ON in BIOS, turn on TPM or PTT in BIOS to continue installation.
