Question HARDDISK WONT SHOW UP AFTER INSTALLING NEW MOTHERBOARD AND WINDOWS 10

[whiter0se]

so i've been using an old motherboard with an 240gb ssd and 320gb hdd for storage and it was running just fine, but yesterday i've bought a new mobo (msi a320m a-pro) and now my harddisk is completely gone, wont show up on bios nor in Windows. When i change AHCI to RAID my hard drive shows up on BIOS but im getting this error called "insert proper boot device" so i cant boot into Windows. I am sure that there's no pyshical problem with my hard drive because as i said when i switch to RAID it shows up on BIOS. so what do i do please help i need that hdd
