ok, back to normal.
I installed first Windows 10, and after that Ubuntu and still can boot into UEFI. Thanks again. |

wow ... finally some progress :-)
- removed the nvme ssd - same as before, just black screen :-( - inserted usb with ubuntu something on it, reset, it booted! Well, it was the next media with something to boot from ... - reset, splash screen back!!!! YAY! - booted into Linux, worked - booted into Windows, back to start, no boot screen, no boot into UEFI so it seems that windows screws something up. I will re-install it and hope that will fix it. I also updated my UEFI while i could enter it but this makes no difference ... I will update this thread once i made a fresh installation of Windows. Thank you! |

I never did use Hyper-V. I just jumped over the description, brrr, it even turns your installed OS into a virual machine.
So only after a very well preparation of myself before installing that... I would remove the nvme too for testing, in the hope that Hyper-V did not change bios settings and just uses a hook mechanism to get the control for bios access. And i think you have to get support from Hyper-V and UEFI shell experts. I will leave this thread but i wish you good luck for solving this issue. |

No, i didn't. That was in the part how to enable it on that page (which I never did, seems Hyper-V did it on installation), i only used the part below "Disable Windows Defender Credential Guard". Any Idea how i can check if UEFI lock is enabled? |

So you configured "Enabled with UEFI lock" In the Credential Guard Configuration box as described in the Microsoft article?
=>> Then you should know what you have to do! |

I installed and tried boot to uefi (from ASRock page). I reboots to a black screen and nothing happens. If i press ctrl alt del it reboots into windows. (i assume it reboots, i can't see anything)
I also disabled fast boot, it was indeed activated, but it makes no difference. (i never touched the setting before) |

just a rough guess are you set to quick boot thats the only way you cant enter bios
either disable quick/fast boot or isntall boot to uefi on windows |

Hi,
Before: i have Windows 10 and Linux on the same nvme ssd, everything fine. I installed Hyper-V which screwed up my VMWare installation and since then my problems started. First Linux stopped working, boot never finished. Next VMWare couldn't start my VM anymore because of this: https://kb.vmware.com/s/article/2146361 So i did everything described in the Microsoft article and that caused the disappearance of UEFI. - if i do nothing the system boots normally into win10 - i can't enter the UEFI with F2 - there is no boot "screen" with the bios information anymore (was in text mode before) - last bios version was 1.40 - no OC, most settings default what i already tried: - removing the cmos battery and bridging the cmos reset header (first battery, than only cmos header and lastly i tried both). - Restart to UEFI ver:1.0.6, nothing happens, black screen after reboot - i removed all devices i could, now only nvme and GFX card (and USB stuff) - ASRock Live Update isn't showing any bios updates, only drivers (yet, 1.70 is on the webpage) so ... any ideas how to fix it? I searched the documentation, it seems there is no bios rescue mode or bios install without entering the bios? appreciate any help, thanks! |
