Trying to make pf sense work

Hey Logan, Love the show. I recently watched you episode on how to install Pf sense and somehow something went terribly wrong,. I tried different ISO's thinking that might be the problem but I can;t seem to get it to work whatever I do I followed you instructions to the the T but when I press 1 at the beginning I don't get the option to to press 99 to do a regular install. Instead I get a lot of text and eventually it asks me for Vlan names which I don't understand. If you could help me with how to figure out what I'm doing wrong I would really appreciate it. Thanks for your time.

That is because you are booting off the CD. When it prompts you to select a mode, i think it is either i or L. That will put you into installation mode. You need to be quick on that. It goes by fast
