pfSense Installation and Configuration
1. First visit the pfSense download page and select your computer architecture and platform. Here I’ve chosen “i368 (32-bit)” as my computer architecture and platform as “LiveCD with installer“, but in your case it would be different, make sure to select and download correct architecture for your system.
2. After selecting the architecture and platform, you will get a list of mirrors to download, make sure to select nearest mirror link to download the image from there.
3. After download completes, the downloaded image must be burn to an CD/DVD media as an ISO image before we start using it. You can use any CD/DVD burning software to burn the image to CD/DVD media.
If incase, you don’t have an CD/DVD drive, you can use Unetbootin tool to create a Live bootable USB media or if you don’t want to follow all these procedures, just go the pfSense download page, there you will get pre-created bootable pfSense images for you USB media, just go there and grab the “Live CD with installer (on USB Memstick)“. Don’t forget to select USB console type before downloading…

10. Next, it will ask you to format the selected disk, if it’s new disk you should format or if it contains any important data you should take backup before formatting the disk.
11. Choose the cylinder size and heads, here I’m using the default settings option ‘Use this Geometry‘ to move forward for the installation.
12. On the next step, it will prompt you a warning about disk format, if you sure about that the disk has no data, just move forward with the selection.
13. Now it’s time to partition the disk.
14. Next, select the partitions you want to have on the disk and enter a raw size in sectors, then accept and create the partition using the specified size or you may move forward with default options.
