Getting a USB bootable to boot up

New to this Not sure I’m even in the right spot I have been trying to copy TrueNAS to a bootable USB using Rufus and Belena Etcher Everything seem to go good no errors but when I try to boot up I get a media test failure I have tried to boot both Core and Scale This is being installed on an HP Compaq 6000 Pro Anybody have any ideas for this problem If I use a Dos bootable USB it will boot to command prompt Thanks

Have you tried using the USB to boot a different computer?
I have made USBs with both tools. Rufus, tried both ISO and DD writing method?

i think i ran into that once try usind dd in ruffus turn secure boot off worked for me :slight_smile:
