do you have a way of trying the CD in another computer. when i tried to boot up pfsense on my laptop it didn't like the bootlaoder and basically was skipping it and going to the next device. i was reflashing my usb flash drive multiple times thinking i did something wrong, but then i tried it in a dekstop PC and everything worked. So it seems some chipset's dont like the pf bootloader/
