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.

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)

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

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.

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.

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.

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]
