DragonFlyBSD

Hi, I'm trying to install DragonFlyBSD on my computer (Dell Inspirion 5720) but I get this error, and instead of booting it enters debug mode. I tried to do some step commands to see where the program is going and I saw that it continues with calling a fumction called "boot" so I guess it tries to boot anyway, however if I enter c (to continue the running program) it will print some more things and then stop responding.

Thanks!
