Recently my replaced old, dead mobo with an ASUS rog b450f. When I reach the BIOS screen to get ready to boot, only my DVD drive is being detected as bootable. I've gone through a whole mess of troubleshooting within the BIOS that I read from other threads but I'm still stuck. This mobo has 6 SATA ports and I've been trying all of them yet only the DVD is showing up as bootable (it's also showing that the port is being switched from 1 - 6 in the BIOS). Some people are saying my HDD is fried but I'm trying to rule out all other possibilities before going and replacing it. Unfortunately I do not have access to another PC to test my HDD there. Anyone else have this issue before?
