following acouple of guides here still getting black screen not sure what else to try?

ive tried a few different radeon cards and also different pcie slots to see if that makes a difference

 

 

^^ from the video above i tried this but still no go

 

dd this in your syslinux/cfg or try it out first and add it in your GRUB before you start UnRaid. video=efifb:off

 

My line looks like that: label Unraid OS No VGA menu default kernel /bzimage append pcie_acs_override=multifunction video=efifb:off initrd=/bzroot
