So I installed a m.2 ssd on my ACER NITRO 5 SPIN. I used the Samsung Data Migration tool to clone my OS onto my ssd. Now when i open the bios it only show 1 drive, either hdd or ssd. When both are enabled through SATA, it boots from HDD and no other device is shown in Booting menu. And when I disable the hdd, system boots from ssd and works flawlessly. What do I do to use my ssd as main OS drive and my hdd as my data drive. Any leads would be appreciated.
