If you’re not too computer savvy, it can be confusing to know where to locate the pfSense installer files and which one to choose as well as how to actually install it on your mini PC. The next steps walk you through the process.
Go to https://shop.netgate.com/products/netgate-installer and for the Installation Image option choose AMD64 ISO IPMI/Virtual Machines in the dropdown. You will have to add it to cart and go through a checkout process even though the cost is $0.00.
Once downloaded, if you’re using a Linux, simply run gunzip <file_name> using terminal while in the directory where the
downloaded file is located. If you’re using Windows, download 7-Zip and extract the file.
The file is a .iso file and can’t simply be copied to USB disk to accomplish the installation. Plug in a USB drive in your Admin_Device and if you’re using Linux use the Disk utility to Create Disk image or download and install balenaEtcher to handle this. I prefer balenaEtcher as it makes it very easy and has checks to make sure you’re writing to the USB drive and not your hard drive by mistake. If you’re using Windows, download and use Rufus application to do the same.
