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!]]> Thu, 17 Oct 2019 13:59:21 +0000 https://forum.asrock.com/forum_posts.asp?TID=12677&PID=69050&title=cant-boot-into-uefi-bios-x570-pro4#69050 https://forum.asrock.com/forum_posts.asp?TID=12677&PID=69047&title=cant-boot-into-uefi-bios-x570-pro4#69047 Author: Ray62

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?]]> Thu, 17 Oct 2019 11:23:47 +0000 https://forum.asrock.com/forum_posts.asp?TID=12677&PID=69045&title=cant-boot-into-uefi-bios-x570-pro4#69045 https://forum.asrock.com/forum_posts.asp?TID=12677&PID=69036&title=cant-boot-into-uefi-bios-x570-pro4#69036 Author: Ray62

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)]]> Wed, 16 Oct 2019 19:40:42 +0000 https://forum.asrock.com/forum_posts.asp?TID=12677&PID=69024&title=cant-boot-into-uefi-bios-x570-pro4#69024 https://forum.asrock.com/forum_posts.asp?TID=12677&PID=69023&title=cant-boot-into-uefi-bios-x570-pro4#69023 Author: gizmic

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!
