The following article will guide you on what to do when the device is not booting up correctly with VOS installed:


the First, Console in the appliance with a laptop connecting to the console port

Make sure the following settings are correct:

  • Correct COM port (Check the Device Manage to find the correct COM port)
  • Baud Rate: 115200


With the above two, we should be able to console into the appliance but if it is still failing

Make sure the following are checked

  • Good working console cable
  • Check with another laptop 


If you are getting the following prompt on the console or the OS is not getting detected



Make sure the following condition is checked

  • Boot priority


How to enter into BIOS

  • Connect your laptop to the Versa appliance using a console cable.
  • When the appliance is booting up, press the Esc/Del key to interrupt the boot process and enter BIOS mode.
  • If you don't get the Esc/Del option during boot up, or miss it, power cycle or reboot the appliance to see the prompt again to enter into BIOS.


Go to the BIOS menu > Boot option

Make sure HDD/SSD is getting detected as shown in the below window


If the HDD/SSD is not getting detected then it means an issue with the HDD/SSD

Eg for such cases


In the below image, we are not able to detect Hard Disk 5 but only able to see Hard Disk 3




In this case, you can try doing the below and check if this helps


Option 1:

Go to Save & Exit

Select restore default => then select Save and reset

The system system will reboot. Then, go back into bios and check if it's detected in both the Boot page and Save & Exit page


If option 1 doesn't work then do option 2

Option 2: 

Power cycle the box once and check again if it's detected after the power cycle (Remove all power cords => wait ~ 1min => plug-in power cords)


  • If the HDD/SSD is getting detected upon power cycle then make sure HDD/SSD is getting selected as Boot Option 1 or 2. 



Once the ISO installation is done successfully, you should be able boot up with VOS.


If HDD/SSD is still not getting detected then it is an issue with HDD/SSD which is not getting detected. If it is CSG device, collect the information mentioned in the document here and check with support:
