Hi all, so I recently bought a couple of t3500 dell workstations at an auction for like 10 bucks a piece with no ram or drives ect, and I can get them both to post just fine but for some reason they will not boot. I've tried booting off of a windows USB and also off of a drive that already has windows and it passes post and hangs there with the flashing underscore. I've tried turning off fast boot and making sure that the right boot device is set, and also setting the sata mode to ahci and IDE and it will not boot off either drive. It recognises they are there. Any ideas?
