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. ------------- asrock b650m/hdv.m2, ryzen 7700x@85watt |

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. https://ibb.co/097cbW6" rel="nofollow">  ------------- asrock b650m/hdv.m2, ryzen 7700x@85watt |

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: https://www.youtube.com/watch?v=4awsXR8STUo or if you use linux edit it with efibootmgr. https://ibb.co/6mrpcSK" rel="nofollow">  ------------- asrock b650m/hdv.m2, ryzen 7700x@85watt |

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.  |

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. https://ibb.co/vzmF6Lb" rel="nofollow">  ------------- asrock b650m/hdv.m2, ryzen 7700x@85watt |
