Im trying to have a dual storage setup ssd + hdd but my SSD that contains my windows OS disappears whenever I plug another drive(hdd). So far I've tried plugging in 3 different hard drives and I still get the same results. On boot it displays "Error: no boot disk detected" etc etc. And when I go to my BIOS, the hdd that I just plugged in is the only drive that's visible on priority tab. However my SSD shows up on the miscellaneous tab on the bios, it says what port it's plugged in and other details as well as my hdd. I dont think it's a problem on ports/cables because my pc works completely normal when I unplug the hdd. I've tried plugging the hdd on all ports available on my motherboard as well as my ssd. My motherboard is Acer veriton s6620g (its kinda old). I've also tried going to my motherboard's manual, no luck.
