I've tried both USB and DVD and neither will boot. It takes me to the boot screen but just has a black screen with the flashing white underscore. Doesn't prompt me to boot or anything. I've changed around the boot priority so its configured properly for either USB and DVD depending on what I'm trying at the time, so that isnt the problem. I've tried changing around the SATA slots the Disc Drive and HDD are in and that hasn't worked either. Any help would be hugely appreciated. Thank you for yalls time
