Reinstalling pfSense CE Software¶
- Read and follow the Netgate Installer instructions to download and run the Netgate Installer which can install pfSense® Community Edition (CE) software. 
- Write the image to a USB memstick. Locating the image and writing it to a USB memstick is covered in detail under Writing Flash Drives. 
- Connect to the console port of the device. - See also - Connecting to the RJ45 Console Port. Cable is required. 
- Insert the memstick into an open USB port and boot the device. 
- Follow the instructions on Installation Walkthrough to install the software. 
- The installer will then prompt to Reboot. Select Reboot and press - Enter. The device will shut down and reboot.
- Remove the USB drive from the USB port. - Important - If the USB drive remains attached, the system will boot into the installer again because by default the system firmware is configured so that a device plugged into the USB port will be booted with a higher priority.
