Reinstalling older NGFW version after 16.2 install

If you are trying to install an older version of Untangle after installing version 16.2, some additional steps are required to clear the partitions from the device. This should not be necessary on any pre-16.2 install which has been upgraded to 16.2. It should only affect fresh installations of 16.2 itself.

Please be aware that this process uses third-party software, which Untangle Support cannot assist you with outside of the steps outlined in this article.

 

Create a Live USB of GParted: this is partition management software that will allow us to delete the old partitions. Gparted Live USB setup instructions can be found here:

https://gparted.org/liveusb.php 

 

1. After creating your live USB, plug it into your NGFW hardware and boot from the USB device.

2. Select GParted Live (Default settings) from the menu:

4. Pick your preferred language.

5. Press Enter again after selecting language to start GParted.

6. Once in GParted, delete ALL partitions in the list:
