I just upgraded my rig:
Ryzen 2700x
Asus ROG Strix B450-f
16 gb corsair vengeance lpx RAM
Asusr rog strix gtx 1070
and a 650 w psu.
I have three drives, a 1 tb hdd, a 256 gb ssd and a 500 gb m.2 nvme ssd.
When i first booted the system only the m.2 and hdd showed up in the boot settings in the BIOS, i have windows on my ssd so i shut everything and checked all the cables and such. I tried different sata cables for the ssd and tried plugging them into different slots to no avail. When i tried plugging the sata cable from hdd into the ssd, the ssd showed up in the boot menu, but the hdd was gone. I managed to boot and update my drivers but nothing has changed. In windows only the ssd is showing up. Im sorry if anything is unclear... im super tired. I'll highly appreciate any help you guys can give me, thanks!
