HDD not showing up in Catalina

[JoshHT]

Hi everyone, i have successfully installed Catalina since last year (August 24th to be exact and it was the beta version), all updates went smoothly. I have to SSD one for MacOS and the other one for Windows. I also have two HDD for backup inside of the computer. Everything was working perfectly untill yesterday. I can no more see the HDDs on the MAC part. It boots normally with no issues, the only problem is that it doesnt show any of the HDD in it. I checked the windows and saw that they are all there and working fine, I also checked in the bios and they are also there. But when I look in Disk Utility I only see the SSD drives.
I did this so I can work and game on the same computer, now I can't work on the Mac anymore.

Please help, I have work to do and like a dumb I did not have any other backup of my work :'(

My specs:
i7 8700K
AMD SAPPHIRE 64
16gb DDR4 3200Mhz
Aorus Gaming Wifi Z270

iMac 5k 18,3

Okay. Just had to fix the bios settings. I did everything all over agin. AHCI vt-d disabling fast boot and secure boot etc. I dont understand why or how the settings in the bios changed but changing them again allowed me to boot normally again.
I took the opportunity to save the bios profile just in case that happens again.
