Strange behaviour with mobo (new).

1. In the BIOS the screen is gray background and white text
2. If I Save Changes and Exit it will return to the BIOS
3. I have two SSDs (bootable on old hardware). In the boot tab, if I enable CSM so that I can explicit boot from SSD the system will hang at a grey screen
4. The DRAM and CPU post status lights will light up for a short while but then turn off. Everything is detected correctly (Ryzen 5 / 7600) + 32GB ram

[BIOS 1.17]

Just upgrade the BIOS to the newest one.

Mine didn't even boot with 1.17 and did only after I updated the BIOS using the flashback function.

For me the windows EFI installation was autodetected by ASrock bios, but I had to manually add linux grub bootloader using efibootmgr.

the bios is black background and white letters - like in the picture in the right.

You have a problem with booting a OS from nvme drive?

are the drives visible from the bios?

what OS you are trying to boot precisely? CSM is a legacy mode. You can disable CSM (even should) if you have UEFI os installed on GPT partition.

anyway i think you might need to add EFI entries to NVRAM. Normally OS while being installed (actually a bootloader) is making such entries in NVRAM and UEFI bios knows what EFI files to boot.

You can try to just run the windows installation pendrive and make a startup repair.

Otherwise manually add such entry to NVRAM using bcdedit in command prompt like a guy in this video:

or if you use linux edit it with efibootmgr.

I'm thinking that as well... I'm making a boot USB right now. Upgrading systems small differences is such a pain!

The SATA SDD was being detected in the BIOS but not as a bootable drive (previously being used in Win10)

i attach the picture of the motherboard bios.

you can see the bios reads the EFI bootloader files how as they are set using efibootmgr above.
