I donwloaded pfsense live cd 2.1.3 and now I want to run pfsense from an usb cdrom drive.
It loads a while and than crahses with "unable to mount ..."
I know I have to choose boot option
3 in order to boot from an usb cdrom but I don't see this menu.
The computer just boots. Do I need to press a specfic key to bring up this menu or is this maybe missing on the current iso?
